Hello! Interesting idea you got going. It's not bad, but off the bat from playing the demo, I'll say that the CPU needs to actually attempt to grab the player, grabs need to be easier to pull off (maybe nix the special bar or make it cost less), and grabs need to decrease the opponent's health instead of increase it. Also, would be nice if you threw some optional ground recovery in there, but that's just a personal preference.
Kudos on actually having a demo though! There are too many of these small games that don't bother having one.
