Finished it! Finally!
Two things I didn't like:
1: The music was very unfitting. It seemed a little too boring to me, and aside from the final boss, it was way too slow and peaceful for combat, in my opinion.
2: The game got repetitive after a while, and there were not a lot of "expectation gaps"
I would have really liked it if some more mechanics were introduced later.
Aside from that, awesome game, with a really cheeky idea behind it!
KEEP! MAKING! MOTIVATING! GAMES!
