In prismatic refraction, strip bare their souls
And show me the shape of the human heart.

The world is not as it once was.

Daemons roam the surface as though it was always theirs, staking claim under the guise of cohabitation, and humans find their institutions slowly eroded by daemon control. Commerce, agriculture, and even medical have come under their jurisdiction.

At the forefront is the prestigious Eirene Institute, a new age of mental healthcare. 

You are the Shepherd—your job is to assess poor souls in need of succor and determine if they are a fit for the Institute.

At least… that’s what the humans know.

How you define your role is up to you alone.

This game is indescribably cool. Kudos. I will happily donate when I can

Thank you very much! :D

I've only finished one route, but this has been a very fun experience so far! Will definitely come back to it (when I have gotten through the other sinners!)

Thank you so much! We’ll do our best to provide a complete experience on the next build!

Niko keeps breaking my game but i don't even mind atp. from what i got to see its super gorgeous and some of the options were EVIL !! In a good way. I liked it, will definitely come back

Thank you so much man!! We’re so glad you enjoyed it :D

Adored what I got to try so far! (Hit the end of chapter bugs hah) I wanna give it another look once your first round of fixes come out - I love the premise, the art, the design, in awe of everything you got done in a month for the jam! I will definitely come back to this to see all the sinners down the line!

Thank you so much for playing and we’re glad you’re enjoying it while it lasted. We’re working on version 1.0 and hope to release soon.

My game broke... It just kept looping around the detain, let go, and keep choices.

Hi Dr. Crimson, we’re currently working on a patch to fix all these issues!

Another Iris to ID game!!! I'm so happy to see another spooktober entry by the team and lo and behold, the writing and art are both fire!!! It got me immersed into the story so quick and I'm really just in love with the lore building, the world, and the characters so far! The idea that we're playing as a daemon and the first narration comes from a human girl who's distrustful of them (for good reasons I think) creates a whole dilemma of morality. Yet even still, not everything in this game is as easily decided as black and white, and that works really well for this gameplay where we have to pretty much judge these characters!

Aside from that, the visuals are amazing, the soundtrack is an absolute BANGER, and I'm addicted to the gameplay. I'm a sucker for games like these and you guys did an amazing job nailing it and bringing it to live!

However, as much as I loved it, I also have a few issues with it. It's mostly issues that I think is caused by the tight time limit, but I still want to bring it up because I'm REALLY anticipating the game's next build!!!

While the UI looks very sleek, modern, and appealing, I think there are way too many moving parts in it that it makes the menu pretty tough to navigate. I think the slider button is subtle and doesn't contrast the bar enough, so it took me a few seconds to register where I'm at in the bar.




[spoilers for Noemie from here on out, spaced out in case someone wants to go in blind!]


I also picked Noemie first (um, probably a bad idea since she's good at talking... but we ball), and I don't think I can proceed with her judgement? I got to the last part and it throws me back to Rais' verdict part (this is me going down the "look at her record and dig into her past" route).


When I went the other way (pleasing Noemie and giving her what she wants. I think I failed at this interrogation), it takes me back to her last interrogation scene.

Picking the dialogue options in her last lock chain also brings up this error

I've only gone down Noemie's case so far. I may be back if I encounter more from the other cases.

But despite that, I still really really love this game and the potential behind it! It's still VERY impressive , charming, and I'm just in awe with every aspect of the game! I can tell a lot of passion, ambition, and love is poured into the project from all parties involved and it definitely shows! I'm super duper excited and will definitely be keeping a close eye on God's Specimen Box! Thank you so much for all your hardwork and I hope the team has a good, well-deserved rest after the development period!

Edit: Adding in my specs! I'm on Windows 11, 12th Gen Intel(R) Core(TM) i7-12700H (2.30 GHz), 16 GB RAM. I hope this helps and lmk if I can provide more info that can help with bug fixing!

Hi Sylvan! Thank you so much for the kind words! Thank you very much for the in-depth bug reports too.

The UI is something we’re currently finishing! It wasn’t completely implemented so it’s a little bit strange right now. We’re doing our best to release a patch ASAP!

Really enjoyed the story and characters so far! I think I encountered a bug:


Thank you for the bug report! We are currently working on a new polished build!
