This game is pretty short and simple. I found it fun and even played it through more than once. It was created for a silly contest and as such is fairly silly itself.
The graphics for this game are only kind of good. The total lack of a battle background really hurts this game considering the battle is the bulk of the game. So a plain black background seems lazy.
The actually battle itself is pretty fun, and you can tell that some thought went into it. Though, I think more could have been done here, I like the short 1 boss style this game has. It's a very solid boss battle and was not only a bit challenging but was also fun.
I'd recommend giving this a look, but don't expect too much.
