Great work, I'm really impressed by the state of the game so far. A couple things could be changed/fixed though:
-You cant bind your controls when playing with a Gamepad
-When dying while charging a shot the charge animation stays on screen when fading to black
Mega Man:
-Shots should travel across the entire screen by default
Bass:
-Should have a double jump
- Shots SHOULDN'T travel through walls
-Bass "Charges" a shot when firing, I dont know if this is intentional or not but the sound is REALLY annoying.
P.S It would be really funny to add the "Book of Hairstyles" item from mega man 9 and 10 to the shop to play as helmetless mega man which makes you take double damage, it would be really fun for challenge runs!
