A very smooth experience, and a great platformer! I found the bouncing cheese piles to be satisfying to jump on. The soundtrack too was amazing. Good job at that.
In the boss, i did find the untelegraphed push away from the platform a bit annoying, cost me a couple of attempts, but I did manage to beat it with full heath in the end.
The setting of the game feels nice and polished, and even in the afore mentioned boss, the design was good. I was scared there would be a second phase after the mouse started flying, glad that didn't happen. (If you make an after jam version, you could add that though, just sayin')
