hey bud! finally got around to playing this. here's what i picked up on after playing (i won't comment on combat since it's obviously not done yet from an animation perspective):
i love the painterly style! the enemy names/concepts are really cute too.
full-range controls might be better than tank controls. i don't know if that's difficult to implement but it's a lot freer feeling. also, the tank controls combined with the swingy camera made me super nauseous lol
enemies can not only follow you from anywhere on the map, they can attack you one after the other. you should give the player a little invincibility time after a fight.
that's about all i have to say. good luck on this!
