When you start the computer, click the flag twice. Only play one music at a time or it will glitch the sounds when you stop one of them. If any of the sprites are misplaced or hidden. Try clicking the flag again. You play the game with your space bar as the jump button. If the obstacle in Jumpin' Cube is gone, click the Flag.
Click the apps and see what they have to offer!!! When ever you are not in the game. Do not touch the space bar. It glitches the game sprites.
