Get as far as you can. Upgrade your cars tires, fuel use and engine to get past tricky hills. Use the arrow keys to move the car, b to brake and e to empty fuel tank if you absolutely can't get past a hill and need to upgrade your car first. Don't let the spikes pierce your fuel tank
The physics are really bad. I'm warning you. Don't ask me why the car can jump. I made this long ago. very bad ngl
