Much better than the current one, kickflow, I just think you should redo the ground pattern, make it stand apart from the block forts. Also the ramps are a solid color, no? Or I think they're striped, not checkerboard.
Also I really dislike the cars, they're quite ugly. You should design a go-kart that has a small tank turret in the back where a teammate rides in, while the other person drives.
