Double-click Jumper to open the game. You can drag around the window, fullscreen it, and close it just like any other operating system. Click the speaker icon to change the volume. When in the game, use the arrow keys to move
In the future, I might add a calculator, and the ability to minimize windows. The Jumper game uses manual collision instead of the <touching> block so that you can rescale it and drag it anywhere without any collision issues :D
