Hey, my first challenge entry. check that out.
edit: NOW WITH ANIMATION :D
Anyway, think Excitebike, since thats the general idea behind it. Except there are specific places and not just "if you finish before this time your in 2nd" etc.
The bubbles, like the stripe things in Excitebike, lower your engine's Temp so you can keep on boostin', except they disappear for a while after someone gets them
Unlike Excitebike, the enemy racers will deliberately aim for you and will take the bubble powerups. And instead of ramps there's spins and tricks or something... didn't really work out the logistics of all of it...
Hey! I liked this pallette and idea so much that I had to go and make a vector version too!
