I really like the idea behind this one, it's actually kind of similar to our game; multiple states!
I did notice that I could jump forever as the cat and as the mouse, I'm not sure that was meant to be that way or not. Before I noticed it the clock jumps seemed really difficult, not so much after I could swim in the air :D
I really like the concept, and I can already see the puzzle platformer aspect of being able to switch between various forms that have specific abilities. As a platformer, that would be a really fun game loop. Congrats on the jam!
