Pretty cool game! Took me a while to figure out that yellow actually heals me XD. As others have mentioned, the tutorial boss was a bit too difficult. The other two bosses seemed fine to me. The mechanics of the bosses are interesting, and I really appreciate time slowing down when the skill wheel turns (saved me a few times). There's room for polish, which I'm sure you'll do when the time comes! Even at its current state, I had fun playing it! Well done, and good luck!
