The visual and sounds are nice, I like the background animation during the boss entrance and the opening cutscene. The gameplay are nice too, the claw destorying environment is pretty cool.
The bosses are fine, those I feel like the damage of the explosive attack from the second boss is a bit too much, and there is a bug where after I restart, I enter the bird boss right away without any weapons. Still, the first two boss are fine.
Anyways, nice game!
