Play this classic dirtbike, with 40 levels to complete, and you can create new ones! The game has a comprehensive level editor, so you can create your own levels if those that come with the game are not enough for you!
When you race: arrow keys to move; use the A key for nitro, S key to slam on the brakes, D key to jump, R key to restart from the last checkpoint. There's many key combinations for extra tricks: arrow keys left and up combined; arrow key up followed by S (slam on the brakes) and arrow key right; arrow keys up and left combined with D key; etc. (you should try all possible combinations to find all available tricks). In the level editor, use the mouse to interact; it's an easy to use editor if you have experience with similar tools; if not, it will be better that you just play the 40 levels already available in the game!
