I did not like this. In terms of graphics, it wasn't that bad. Then again, there was really very little going on here. It was just you riding your bike. I can understand why a lot of others didn't like it. I'm not much of a fan of bike games to begin with.
I'd rather do it in real life. I guess the sounds weren't bad. With all the games out there, it's hard to see how this stands out. I'm glad I've never tried to bike over rocks like that. It is not a rewarding game.
