Genuinely such a cool concept for a game. I can imagine it can be tough to balance having the attacks the boss uses against you as skills to use for the next boss, and I think you balanced it pretty well!
I do wish the game had an end though, instead of just going on forever, because right now it just kind of gets boring after beating the bosses 10 times
The art is really nice, and I think the music fit the game very well, especially liked the music for the clown! Really cool game
