Entertaining and addicting yet relaxing game.
Drive car, have fun, push boxes or bump into them, in order to clean the mess and throw boxes over the edge. Do not let boxes pile up.
Do your best to keep up with speed and new boxes different colors and sizes.
When boxes get stuck, gravity will help a bit, but you should bump into them and help gravity. It's fun!
As you progress you will get a new better car, but ... We will not tell you all, try it and find out.
