Code	/*************************** I know that this game is far from perfect, but it is (I hope) unique in Khan Academy so far. I challenge you to complete this game with the variable on line 36 set to 50. Put your name here - Name: ________. Your goal is to get to the flag at the end of the ride. You lose if your cycle overturns or falls down. CONTROLS:- 1) RIGHT and LEFT arrow keys to move forward and backward. 2) UP and DOWN arrow keys to lift front wheel and back wheel. 3) Sorry, but I couldn't add mobile capacity because of the lag (though a computer can easily handle it). OTHER INFORMATION:- 1) Beware of eerily distorted terrain (it is very buggy), but it is almost always followed by a smoother section. 2) Please tell me if you find any bugs in 'normal' areas. 3) Your score depends on the time you took and the distance you covered. 4) Unpassable terrain MIGHT occur. 5) The sun's progress on the screen tells you the distance that is left. 6) Every bump in the ground is a accurate representation of the way the wheels will bounce. 7) You can use WASD too.
