You forget to add a roof right to the showers, and if you want to people to not go in, add barriers ! Or maybe you want no roof, in that case i didn't say anything haha. Nice prison btw !

Впервые в жизни выкопал "метро".

This sound just like a place in a book that was a mental pennitentary

nice prison i like the improvisations with the decorations like using doors for gravestones, it's also hard but not too hard
