I think - brick sound for rat sliding is so funny XD
Cute stuff, I enjoyed playing this. Really liked that we are running in a box.
I think it would be nice to make obstacles a bit different. (like verious shapes where you need to jump in. ) And maybe sliding having limits, as I was using it most of a time.
I wasn't expecting that you restart whole game if you died 0.0
I was just "What's gonna happen if I run into mouse trap?" - "You died, start again"
But anyway - good stuff!
