good
I only had a few problems with it, one if you beat the computer fast you don't get a bonus to bring your highscore up toothers, you should be scored on time beated as well, I beat the computer in under three minutes with a score of 3000 something. Which even though I obviously whooped it, left me off the highscore list.
that makes it unfair, which means to get a high score you have to let the computer gain on you, and keep the game going.
