Never mind the stealth and the jumping in the trees thing! Ride your bike and drive off with the towering city buildings in the backdrop. Bike Ninja is a dirt bike game that will take you into a field lettered with small but terribly formed humps that you will crash to if you arent careful. You shouldnt take your fails for granted and you should quickly learn from your mistakes because repeating the same wrong might cost you a game over, then youll have to repeat from level 1. You cant always accelerate along the field, and you should sometimes hit the brakes and drive slowly so you get just the right speed to avoid crashing. Up arrow key to accelerate, Back arrow key to brake or reverse, left to lean backwards and right to lean forwards. You can always pause the game with the P button and hit next with the space bar.
