ooooohhh...... 5.5 i'd say.
normally i give 'pong' games around about a 3 or 4... but you actually DID something with this game, so im happy. the graphics were pretty cool, and it was a welcome change from the normal 'black background/white paddle' that we are all so used to.
the different levels of difficulty were good, and i think that the endurance level you added really helped this modification game along. im pleased with the result.
5.5/10
(THE THUMB: slightly up)
