Really good visuals and music and it was fun, I beat it. But man the difficulty of the bosses is really high. The first boss with the rolling attack and rapid fire circle bullet patterns is insanity :D Increasing the movement speed on the player would also be beneficial I think. Personally found the last boss the most fun, as its moves felt the most fair. Second boss had a cool design, but really hard again. Didn't really find myself using the melee attack either. The color mechanic was really interesting and it was fun needing to shoot with the right colors.
