Click the green flag and the rest is pretty much in the program. When you click the "Play" button then you have to jump over the obstacles, but the same costume of the obstacle will go on until you restart.
The game I have to thank for this program is the no internet game, which you can play when there is no wifi. When there is no wifi on then type in a random URL and then click the space bar or use the arrow keys. After that you enjoy that game.
