nice try
4.17??? This game is overrated. For one, the hit detection, moveset, and physics are all atrocious.
Hit detection: When you press the attack button, but your opponent is four inches away from you on the screen, they get hit anyways.
Moveset: there is only one attack button, and characters are extremely limited in what they can do. Especially Kirby, whose stationary move is a completely useless transformation instead of his signature "swallow" move.
Physics: the momentum is about 200% too strong, running on the ground is like running on ice with smooth-bottomed shoes, and you basically have no control when you do a running jump at full speed.
I have to give you credit for trying, but I think that this was a bad choice for your first game to make. It wasn't too bad for a first try, though.
Also, on an unrelated note, never put any Sonic character other than Sonic, Tails, or Knuckles in a game (unless you're making fun of them). Anyone else sucks. Yes, that includes Shadow.
