This actually looks like it could be some fun. Though, am I the only one who finds the "on hit" sound effect to be extremely annoying? Every single time the player hits someone, you're greeted by that noise? It just doesn't sound appealing to me.
It has a clean, colorful and cartoony art style that appeals to me, it also seems the fighters are inspired by different sports. Could be fun to try out, if only for a day or 2.
