Thank you for your detailed feedback! This game is definitely at basic prototype level right now, but I'm still glad I got to enter something. It's the first game I've made with Unity, so it was a learning experience using a new engine, for sure.
I have tons of plans for things I want to add to improve it, especially putting the host himself into the game.
It's funny you should mention climbing out to escape. I wanted to add barbs to the tops of the walls for that exact reason.
