Okay the bug with the cage is so boring it completely blocks from triggering anything anymore...
I thought I fixed it, bug it seems like it's possible to still trigger it by restarting the prison level... I'm really sorry for this, I did not have enough time to fix it :(
The bug when you become stuck in a block and fall afterwards is pretty boring too, but I used an asset's player controller, I guess I can only blame myself for not understanding how to use it. Maybe I could have avoided this by doing one especially for my game.
Thank you a lot for your feedback ! And thank you for appreciating the concept ! :)
