The music are nice, and the visual are cool too, I like the effect of the shock wave attack from the second boss, and the overall graphics of the game. The gameplay are also nice, the player movement feel pretty smooth.
The bosses looks cool, the animation of them are really nice. Tho the damge hit box on the head is a bit too big, I need to run very far away to avoid getting hit, and once it hit you, its knockback will sometime keep pushing you back to the center of the head which is a bit annoying.
But still, cool game!
