Prisoner 134. You have been purchased for testing and are now the property of BioMass Labs. Knowing nothing of the place you have been brought to, your only option is to enter the maze and solve the puzzles in the experiment.

In 2194 humanity has populated the entire galaxy. As our existence expanded, crime became harder and harder to control in the vast reaches of space. As a result, laws became more strict. Government attempts to wrangle the issue bolstered a growing police force and, over many years, the reach of law enforcement grew larger and more aggressive. The general population, simply wanting to feel safe, grew more accepting and the first fully commercially run prison systems took form.

Nearly one hundred years later, in 2290 imprisonment is common place. A blind trust has been placed in the commercial justice system eventually landing every day people in jail for years for even the smallest offenses creating a massive divide between the idea of prisoner and person. Hundreds of commercial prisons and law enforcement companies thrive.

Devaluing of prisoner lives and massive prison overpopulation gave birth to an auction system where anyone could purchase prisoners for any use free of legal ramifications.

Acquired in the most recent bulk order of prisoners for BioMass Labs, you are being shuttled off for study at the Kohate testing facilities. No information is known about the details of the study.

You have been black-bagged, loaded onto a transport shuttle, and are waiting for law enforcement to release you to the company.

The subject is a sci-fi horror puzzle game designed to combine a mix of classic puzzle adventure games with horror elements.

You will need to learn to navigate the complex to find your way to the various puzzles set out in the experiment and discover the reason behind the testing.

You are being monitored by those running the tests and are required to visit a bio-data terminal periodically to record your vital signs and other data for record keeping. If you fail to do so, you will be removed from testing by euthanization.

Is the 2.0 update  or the 2.0.3 hotfix coming to Itch.io ?


It is. I’ve just been swamped with WTTG work so I need to set aside some time to make the necessary changes to being that version over to itch.

(1 edit)

I'm a patient man with a huge backlog so i'm just happy it's on the list of things to do.

Ok so I've encountered two issues this far:

  1. I saved the game right before the monster attacked me, making it spawn-kill me everytime I reload my save.
  2. The monster seems to have no running animation, I assume this is a bug

This was in the current Linux-build here on Itch. Seems like a great game so far!


the save issu is kind of bound to happen if the player isn’t careful. Though that’s sucks. As for the no running animation, that’s interesting I’ll have to look at that. I haven’t seen that in my build. Thank you for letting me know!


Hey! I'm wondering when the Linux-version of the game will be available here on Itch? I'd love to add this game to my library :-)


Hey! I may try to get that done tonight. I have 3 projects going on at the moment so thank you so much for waiting! It’s on steam so it exists I just need to gut the steam integration.

No problem, just excited to see it here on Itch ^^ Will any of your other projects release here as well? If I like this game I'd love to follow your progress here on Itch ;-D


Yes! Now that I have the pipeline figured out. The plan is to be releasing my games on steam and itch with both Windows and Linux versions for future projects.


Linux build is here!

Are there any plans to release the full game onto Itch.io ?


Yes! I actually have a build for it but need to get in contact as they do not allow enough space for the game currently.

I'm just glad you are trying to make it happen. Best of luck getting that sorted out !


you can purchase the game here now! Thank you for your patience :D

Gave it a go...


Thank you for sharing! So sorry I missed this. I've been busy with three other projects but I still shared :)

Don't worry about it my dude. You keep up the hard work on those other projects. Keep in contact  for your future games too. Bless!
