1. Collect more gems than your opponent. 2. Avoid snow. 3. Crash into your opponent to send them off the road. This is a multiplayer game to be played on one computer. NOTE: If you draw, even if your score is larger than the current high score, it will not be counted.
I took the scripts and idea from "Coding Games in Scratch." The images for the road, cars, gems, and snowballs were created by me, and the image of the penguin was taken from the Scratch sprite library.
