Great game, but it needs fuel powerups, and the powerups need to get better and better with each lvl, that way it's still a challenge, but you can make it through the later lvl's without running out of fuel and exploding.
co-op could be easier though
very good but you start to get bored after awhile bUT..... awsome
I'm having so much fun with this game. The greatest is when you get a lot of vehicles going and just jump around like crazy. Good job :)
