For an Unity game, I think that this game is above-average.
Everything seems to be working fine, there weren't any bugs I managed to find. However, it's only good for one or two attempts, otherwise you'll probably get bored of it. The only part that anyone could have a laugh at is "Oh hey, look at him spin, hahaha!". Then it's just "Oh look, they're spinning... and spinning... and spinning..." ad infinitum, which isn't really good for the 2-button kind of a game, considering stuff like Soccer Physics where you can perform some sick shots, or Drunken Wrestling where you can [sometimes] knock a guy's head/torso off his body with your bare fists. I don't think this game has the charm that the games mentioned above do.
Like I've mentioned - It's pretty decent. However, after doing about 2-3 matches you'll probably get bored of it.
