it's okay...
I know you really worked hard on this. and I don't want to be annoying, but this game isn't as fun as I hoped.
the graphics... of course they were good. but you could have achieved the same greatness with simpler graphics. the story was a bit weird, but that's okay. The main problem of the game is it's ability to offer nothing interesting to the gaming world. Basically, most of the time I spent on riding towards a green light, and then riding back. I faced no difficulty whatsoever. this made the game very... boring. and so, my tip is: work harder on game-play. you shouldn't waste your time on graphics...
oh, and personally, I don't like 3D graphics as much as I like cartoon graphics. but that's just my opinion...
