A city on edge as a serial killer roams the streets...

Frustrated by one unsolved murder after another, forensics graduate student Rei Kuroshima decides to get his hands dirty to solve the crimes. He resolves to copy the killings to chase the serial killer known as "The Doctor" in order to figure out how the murders were accomplished. Along with his supervisor Aiden Steele, a detective oblivious to Rei’s identity as “The Copycat” killer, he must piece together a trail of evidence to uncover the identity of “The Doctor.” At school, however, Rei must maintain his normal student life while dealing with his obsession.

Dude I'm so sad this seems to be dead :/

It looked so promising but there are no news anywhere. The last Update was 2020 so yeah I really guess it's safe to say this is not going to release .. :(

(1 edit) (+7)

Sooo... it's been a HOT minute since the last update. Life happens, completely understandable. I wouldn't expect the devs to prioritize this game over their mental/physical health. What I'm saying isn't new here, but I really wish that at the very least, they would be more transparent about such issues. A simple "hey guys, really sorry about the lack of updates, but life stuff is going on and we are taking an indefinite hiatus" would suffice, especially when they have been financially backed thousands of dollars. I joined the Discord and the most recent update I saw was in October of this year, in which the dev basically said what I put in quotes above. While saying it on Discord is better than not at all, I think that they should definitely be saying that where backers and the general public who have been waiting for this for a long time to see. Not everyone has Discord or even knows there's a server for the game. 

I take no issue with the game's development taking longer than expected. Hell, Omori took SIX YEARS, and it turned out absolutely brilliant. I do take issue with the devs not communicating this, which ironically enough, the creator of Omori was guilty of as well. Alongside that is the fact that Omori was Omocat's first game, and First Degree is also Parival's first game. Perhaps I'm being too optimistic here, but maybe it's a similar situation going on in which the development process for First Degree is going to take a very long time, but the final result is amazing. I left an extremely positive review of the demo 9 months ago, so I definitely have faith in Parival to keep that quality up for the rest of the game. 

I wish them luck and success in their future endeavors and progress on this game, but do wish they would be more upfront about the whole process. 

Edit: After rereading some comments, I noticed that some were angry about a side game being finished when the main isn't. I could be wrong, but I don't think that the devs made a side game just for the lulz. It could have been to bring some more money in because the main game was costing more than expected. Again, this is their FIRST GAME. They may have underestimated the time, effort, and money it takes to do something like this.

I refuse to support these developers anymore, and glad I didnt support this. I hate to say it but devs are gonna have a harder and harder time getting their games backed if they have no history of successful releases because so many projects take money and dont deliver. Between this, AMAP, and a few others, these guys just refuse to even give updates and its absolute garbage. If you took money from people, you owe them an explanation, plain and simple. I see a LOT of devs blame physical and mental health, which is fine if you are transparent and honest with your backers, but too many of these guys cut and run and then fall back on "poor me" excuses. We all would be understanding, but not after HALF A YEAR of no response. 


hello devs, pls dont be afraid to make an announcement about things happening on your end. we want to be update rather than being kept in the dark. i hope u guys well and goodluck with real life <\3


Joined the discord server to see wtf was happening with development and the dev has just been on hiatus for half of this year with absolutely no updates on itchio and then answered questions about when the game was coming out or storyline arcs with extremely vague answers. Was super excited for this to come out this year after waiting 4+ years now am extremely disappointed. I wish the people like me who spent money to see this game actually get developed get their money's worth eventually




Well, I think we can safely assume that the game was abandoned(ONE year without news). I hope you will refund your backers 


I feel like the game should be for androids and iOS players 


Android plsss


I really wish y'all'd give an update, even if it's just "hey, so, shit's gone kind of sideways, we need to take a hiatus, we'll be back in X time."


I wholeheartedly agree. The only reason I've been holding back from getting the side story is because there's no certainty (or estimation) on when the main game is released.

I really want to support the devs but getting only the side story before the main game just doesn't sit well with me. Not to mention there's no update in the last 1.5years.

Still hopeful this will be released though.


I've had this game saved for a while and i'm seeing some negative comments I hope aren't true as I had high hopes for this game and would/will definitely buy it when it done


i'm not sure if it's any consolation to anyone who paid for the game, but i actually spoke to paradise, the person in charge of parival. they told me, "We are currently just coming out of hiatus. I didn't want to make any updates because of the lack of progress. I had to... finish school... had to switch writers again. So, we've had a lot of unfortunate circumstances within the last year. We are still trying to get the game finished. I am going to make an update when we have a lot more progress, though it does not seem like it will be for a while."

again, not sure if anyone really cares or is interested, but i'm personally glad to know they're still working on the game.

So, this sounds like "we have another business to do, besides OUR game". If they are sincere, why couldn't they just post the same words here? You know, like any normal dev would do, to stop spreading rumors. They don't even try to fix side story, what could I say else. Gamedev is a very hard thing, and not everyone is meant for it. I couldn't finish my game, so I don't try to post it or sell it. 

I am very happy I didn't buy it last year, when I was wanting and hoping.

(1 edit) (+2)(-4)

maybe i'm simply being too soft, but it is their first game. maybe it's a similar story to a game like omori? first time devs may not have a lot of experience, and may not know exactly what to do, but their final product could still be alright. look, i'm not gonna lie and say i'm unbiased here, i've been really excited for first degree pretty much since it was announced, and i have a lot of sympathy for first time devs. game dev is hard, for sure, and i've supported projects that never came to fruition in the past, but i'm still trying to hold out hope for this one. i'm not sure why the devs didn't say anything here, lack of transparency definitely doesn't bode well. the reasons they gave were having to finish school as well as switch writers, both of which are not easy to deal with. school keeps one busy, and hiring new writers that actually do a decent job is tough. i'd like to keep believing in parival, and especially first degree. again, though, maybe i'm going too soft on them?


It could be their first game. They could be unexperienced, they could be sick, or tired, or busy. BUT! - Is this really so hard - to come here and tell everyone "everything is okay, we are working and game will be done soon" or "we are tired from gamedev and we are not planning to finish"??? This is normal practice and such doing separates thoughtful people from indifferent ones. Because of this I don't want to wait their game or buy existing side story. For me,  will be better to spent money on something not abandoned.


i,,, suppose it would be easier just to come on and inform everyone themselves, yes. i'm not sure why that hasn't happened. i understand fully how this could turn someone off from a project. perhaps i'm too optimistic, but i'd like to keep believing in them.


I wouldn't try to persuade you or anyone else, this is only my decision. It was the game I liked, the game I wanted very much, and now I am disappointed. So, it is only my feeling) 


I feel like the game should be free to download when it's officially finished due that so many people donating and how long it took the game to finally finish not being finished so I feel like the game to be free and for all donators get something in return.


I will be blunt, you are probably some of the worst queer indie game developers out there(despite your game being amazing). It has been almost a FULL year since you last released an official update, people payed around 8200$ to support your game and this is how you treat them. If unfortunately real life probelms are overwhelming you(I really hope not) jusy say that the project is cancelled and try refunding your supporters

(1 edit) (+6)

I checked all contacts and some of them is gone, some - forgotten. Should say, I am glad I had doubts early and didn't buy this game, because it looks like dev decided not to finish the main game))) It is sad, the game is promising((((


Is it to late to pledge to the game cuz im interested in the game

many characters & mysteries (nice visual novel)


The demo looks so great!! Art, characters, everything is amazing. Can't wait for the full game!

I loooooveee itt! I can't wait for the whole game to be out :)) <3

First off:

Parival, I hope your ok and that everything is alright. It's been a long time since we last talked, but I know life was hitting hard last time we did.  Hopefully soon, you will be able to give everyone an update on what's going on and where the game is at. Hopefully, it's still planned for 2021🥰. 

Secondly: I get everyone's anger for the game constantly being pushed back, especially original supporters from way back. But keep in mind, that there are an excessive amount of costs/time that have to get put in to creating these games along with IRL outside factors (mental health, school, other day jobs, having to hire other artists/writers/coders when one bails or has life issues, short on people to help produce the game, etc).

This game is also now twice the size of the original I believe 🤔, and where they had planned to go with it has changed (fyi: they needed more time/money for it, as well as new CGs due to changes in story). I know at this point alot of people are tired of waiting and just want to experience the amazing premise that went into the demo, but as this game was being developed things like story, art and more got changed along the line with also vast changes for what CG work gets put out/writing/coding.

Also: They put out the side game first to help create some more profit to help go towards finishing their MAIN game. That's why it got released first. Another thing to note is they didn't create it just to take people's money and drop the base game. As small game groups go, games can't be their first priority. Life is first. So when you purchase from indie groups/support them. Just know--they may post pone games by 1-3 yrs in order to come up with the extra costs to support the game--unless they are able to account for all of that ahead of time (isn't always possible either, but with experience and time you can get better at figuring out the costs/dates). Also, sometimes releasing something unfinished/subpar leaves people more angry, than if they had gotten a more polished game.

This game will be released, it's just a matter of when. I believe in the developer. They're not just going to take people's money, and drop something they have worked so hard for and even had to release a side game in order to help out with base game profits. Unfortunately, like I said, life is life and it sometimes it's unfair, mean, cruel, just ok,, or great. That's just how it is.


 They let people know that there were some unfortunate IRL problems the past half year since August, and that they needed to take a Hiatus from the game/updates (typically a period of 3-4+ months of leave due to emergency, mental health, physical injury, not enough profits for their work, vacationing to distress, etc). But development has still been progressing despite some life issues. They said that sometime soon they will release an update on their platforms onto what's been going on, and where the game is at now and for the future. 

Also, just a little bit of humanity calling you guys out here. But when someone doesn't post for so long. Something has obviously happened. Rather than get angry, and share hate because you're feeling petty and angry at how often the game got pushed back. Perhaps, it's best to reach out to said individuals, ask if they are OK, and be more concerned about the human being behind the service they provide. Instead of the entertainment you payed for, that has yet to be received.

I know it's hard, especially when you payed for something. But keep in mind COVID since 2019 for some--has made the past 2yrs realllllly bad years for a lot of people--and we're still going through it in 2021. I myself have lost 2 older family members (1 more distantly related, and another closely related) from 2019-present. And some people have not only lost people during the pandemic time period, their economic conditions have collapsed and are barely living right now.

The issue isn't the game being pushed back, it's the complete lack of communication. If someone has given you money for a product you have promised them, then the appropriate thing to do when faced with a setback is to let your customer know of said setback.
It doesn't have to be an extensive, detailed thing. Even just a "Hey guys, due to COVID we are facing medical/personal/unforeseen issues, so the project is on hiatus until further notice." That's it, just a sentence. Maybe a follow-up when you have a more concrete idea of your timeline.

Just basic, simple communication. It is perfectly reasonable for someone who has paid money to be annoyed or upset when they get NO communication about the thing they paid for.

I understand that they've been having difficulties, and I would by no means expect them to prioritize a game of all things, but if you're going to take on the responsibility of accepting peoples' money, you need to also take the responsibility of communicating with them.

Hi! Thanks for your response! And of course! I def agree! Communication is a key role in customer service. 100%! My initial response was mostly to the people that were angry about the push back (and there were) as well as pointing out that there was no need for people to act rude or mean on this server, when we can all act civil. And lastly, I do agree with you to an extent (the extent being: extenuating circumstances we're unaware of) on that notion. A circumstance that could also include (but not related to) being able to not give out a short, non detailed, simple message to inform their public/customers. We as of right now, don't know both sides to the story, and why they may or may not being using this platform (vs the other one) to clearly communicate. The reasons for not communicating clearly (or excuses as some might see it) can range between anything. From Mental health, to even game image. But, I guess we'll find out when they're finally able to let us know what happened and where everything is at for them and their customers! Hope we'll find out soon tho and they're doing alright!


I mean, no, they haven't communicated anything to their Kickstarter backers, either, and the few people who have been able to catch them on Discord have received vague responses or silence. The fact that they were on Discord means they are able to release a short update, but are actively choosing not to and "avoiding the issue," which is not how you deal with difficult things.

It's one thing to be positive and forgiving, but you need to hold people accountable sometimes as well, especially if they've been given $8,000 and can't even be bothered to announce a hiatus.

Exactly. Communication is a key role in customer service for games. Up until a year ago, they were updating us. Then, suddenly nothing. Ironically, likewise...a lot of devs went dark this year in terms of communication. *cough* *cough* "All Men Are Pigs" 🐖 "Are you out there?" Does, this project feel dead? Sure.  Do they have their responsibility to keep the public informed as they took people's money? Yes. Have they been doing a good job at that? No. Are they avoiding relaying what issues they faced, and why? Most definitely. Did they at least notify their Discord members, that they're on Haitus right now? Yes. Should they maybe have updated all their platforms rather then just Discord. YES. 

Like I said, customer service is a key role in how things play our for devs now and in the future, and if they will receive further support or not. But whether or not I have money on the line in a Kickstarter I support, I go in knowing I might just not get what I'm asking for (especially with new upstarts) and that I might no get it at all (was deceived or project failed ex: Man Eater Games), and that I might not want to support said company later on if they ever come back. My original post, had more to do with the fact that people were having no compassion towards each other, and being rude to everyone during these hard times. And they have been. While my second response to you, was in clarification of that and why I choose to be more understanding. Late 2019, 2020, and 2021 have not been easy on anyone. That's for sure.

But like I said, in the end--devs don't get to be excused for taking people's money, and not producing their product, rewards, or communication well enough, or at all. And they won't be excused for it. This all aligns with customer service, and will likely head towards less support for them in the future. But that's the path they chose, and the risk or consequences that come with it. And people don't get to be excused for their words or actions towards each other either. So as to your statement, I'm not saying I don't hold them accountable, because I do. But, I also choose to try and be understanding while also holding them accountable. Of course, that's just my choice and perspective. It's not like I'm asking you to agree with me. I'm just clarifying.


A lot of people have invested their money in the game, and you will not even deign to do updates?Shitty game.


I played the demo and was immediately hooked. Not only is the premise very interesting, but the art style is wonderful, and I am impressed that there is voice acting included. I also like the stress of having to decide what to do in order to not be suspected; it's unique and so is the phone feature. Overall, it seems to be a high quality game, based off what little we have been given. I just had to buy the side game after finishing the demo, and was a little disappointed there was no voice acting in that one (there were moans, though!). I guess the demo just got my standards up too high LOL. I liked it nonetheless, and the twins are definitely my favorite. 

A few of these comments are pretty negative, and I think they are underestimating how much effort and time it takes to create a game like this. I'd rather have a perfected game that takes a while than a rushed one full of errors. However, I will say that it is a little rude to not have an update and be radio silent for months at a time. As far I can see, the last time people got an update was last year in August. I think people would take to the waiting game more kindly if you gave updates more frequently.

Of course, life happens, and we are in a pandemic. But I hope that we get news of what's going on with the game soon. I am very much looking forward to it and will anxiously await a full version, no matter how long it takes!


Dear, dear.. Many people have been waiting during this time, I hope this is not going to be pushed back another year.  Without any updates, people who have invested in funding are losing  hope in this game. the potential idea of this game is so wonderful and  we all hope that the full release will see the light sooner or later. perfecting the game will take a long time its understandable, but  its better to release then continue updating the imperfections that come to your attention. something is is better then nothing right?   As someone who had bought the side game,  I    really want to best for your team and hope that this game can be released so it can strive .

(1 edit) (+1)(-5)

The idea behind this is interesting, but I find how... manipulable the MC is really, really irritating. There are also some kind of cringe-y moments from a consent perspective, which might be a weird thing to have qualms with when the MC is a serial killer.... but still.

Will it be available in Steam?


Don't wanna ruin everyone's expectations, but the main game will likely never be released. The devs for this game are known to be extremely lazy, and the fact that they put more time and effort in side game rather than the main story says a lot. Devs wanted to make quick money  without much efforts. (not saying the side game is bad, but it's definitely low effort for its price)

Having to pay 10$ for a 50k words long visual novel is ridiculous, especially when there are very, very good and wayyy longer visual novels out there you can get for free or like, 5$. 

Seriously. I know i sound b*tchy but it has to be said.

So yeah, don't get your hopes up, pretty sure this is never going to be a finished product, and it was planned to be this way from the very beginning.


Can back this up from having known the lead dev lol


wow, what awful people. Ugh

(1 edit) (+5)

Haven't seen any updates since August even on Kickstarter... I hope you guys are doing okay. I know it's been a rough time. :(


You release a side-game before the full game, what a great idea :/


When exactly do you think the full game will be out?

Its now 2021! and I'm excited  for the release of this game!! Gonna keep posted for the release date!


Is this still in development?


Hello! Is game still in development? I afraid because didn't see any information or updates((( 

(1 edit) (+6)

So I know that it is coming out in 2021 but do you know when exactly in 2021 it will becoming out?

Wait so you play as a copycat killer hunting for a serial killer? or did i read that synopsis completely wrong. 

As someone who played the demo: yeah. Rei is hunting the serial killer by trying to figure out how he does his murders by copycat killing.

......um.....I'm guessing he has a personal reason for wanted to catch this murderer, cuz that just seems counter-intuitive 😅

I bought the side game.It looks awesome. I would recommend making the text larger for the full game.  It is a bit too small and the reading doesn't flow fully. I would not say that if I didn't think it looked awesome. 

Thank you for the feedback! We'll keep it in mind for the main game. 

Show post...

this. this right here is why i love yoai.

played the demo, loved it! about to buy the side game omg

I'm so excited to play this game. I just bought the side game and I'm about to play it now. Please keep working hard! We appreciate the effort!

Darn it, I just found out about this game. I was so looking forward to buying the beta.

Hello! I was just wondering how to purchase the side game? I can't seem to find a link for where to buy it directly?
