Move using the arrow keys. Jump: Up Arrow Left/Right: Left/Right Arrows To double-jump hit the up arrow whilst already in the air. The aim is to complete the course by getting to the end. Do not fall off the map, and do not touch the red. The purple portal is a checkpoint, use it to save your progress. You can only change direction mid-air by double jumping. To wall jump, make sure you are holding down the up-arrow as you hit a wall.
