That Hanzo Cresent sequence is not fun.. the dash gets pretty unreliable when youre dealing with 2 or even 3 of those waves at once.. You should really also allow the player to use the pizza when they are ready to.. Trying to evade the pizza throughout the boss fight is tedious. maybe allow the player to collect them, then keep them in stock (5 max?).. also whats the hit box on Pico? it should really be as tight as possible for shooters. especially a shooter that uses physics and can shoot random trajectories. I had boom shoot across the level only to be killed by them because I didnt notice it fly offscreen
Everything else about the game is great, the sprites, the music, the animation. Using your dash move to power up your gun is also a very neat gameplay element, Hopefully later levels will open up more and allow the player some breathing room for some fun air attacking
