Very neat little game, I liked the "Kaizo-lite" difficulty! The graphics are very nice and the protagonist is adorable, and I think using transformations as powers is very clever. The controls are a bit floaty, but I guess it fits the "ragey" gameplay - the gliding ability was a lot of fun to use with some practice.
The behavior of the enemy cats was quite relentless and believable, and I think they were by far the hardest enemy type - the game got quite a bit easier when they got replaced by other enemies.
I feel like the difficulty level could have gotten annoying in a bigger game, but thankfully I never got stuck long enough to really get frustrated. Overall, very nice job!
