It was interesting, because I didn't even know the computer was playing at first! I thought it was just me playing against myself! I know I at least clicked the screen when the computer started. I admit that is kind of an original idea. I haven't played one of those games like this. It does make it less fun when there are no obstacles or anything.
Wait, I'm thinking of the wrong kind of game. I thought it was fun to get close to hitting your opponent. While not that creative, still good. You could probably brush up on the graphics, too. You bet I recognize that music.
