The object of the game is to get a lot of gems without bumping in to anything. You can bump in to the other car though. This game is a 2-person game, so unless you can use WASD and arrow keys at the the same time, then you should only have one person. The penguin will tell you the rest.
I followed a tutorial by tbate54 on YouTube. If there is any problem with the game, tell me in the comments
