i really like it a lot is it okay if you share to me the project i really liked the mecanics

I liked this concept. I think I found a consistent way to break the game though. By crouching in front of the door, the camera clips through it and you can see the hallway, then I could jump through the door and I would get the message that I was released after, for example, 0 days.

I enjoyed the different outside sounds, though the sound effects often had static or other noise, as well as clicks when they started and ended. Fading in the very beginning and fading out the very end could help with the clicks, and open source programs like Audacity have noise removal tools. Just calling that out in case you aren’t aware. Not a huge deal, though.

Nice job!

It certainly evoked the feeling of being trapped :)

I promise I will never use Unity3D again :p
