It's a cool concept. I like that you can throw the cat through obstacles to get through them.
That being said. The controls are a bit confusing to me. There are too many buttons, and I was often pressing the wrong ones (and it's not natural for me that you can't jump with either up arrow or spacebar). Also it's not clear to me when I could throw the cat and when I couldn't (I guess the player emits some particles when you can) but just a simple UI icon of a cat would go a long way.
Unfortunatly the camera is bugging in some areas and at some point it was doing it so much that I was unable to finish the game (but that's a given in game jam games I guess)
