Read the instructions given at each level. Use one hand to play the game with your keyboard and the other to eat an apple. ;) There's a detector for this program to see what you're hovering over on the webpage. For example, if you hover over the 'see inside' button, there will be a message broadcasted telling you to stop what you're doing because it thinks you are attempting to cheat by changing the code. If you aren't logged in, in editor mode, or in full screen mode some detections won't work.
