Really good so far, maybe a little complaint I have about the lack of shooting animation while in the air, but:
"Animation is NOT being given much work right now, I'm focusing on the moviment mechanics."
So, yeah, that is great, keep it on
I just put some animations to feel a little more like Mega Man. It'd be too much for me to expect that a green rectangle walking around would feel like Mega Man. I think that can be done way ahead, so yeah.
Oddly enough, while adding the sprites to C2, I forgot to include the shooting in the air animation and just left it out anyway xD
