Use the left and right arrows or the A and D keys to move. Use the up arrow or the W key to jump. Everything works in the game. To adjust volume, use the M key to raise the volume and the N key to lower the volume. Click the green flag twice when you want to retry the game when the end screen appears.
To make the pixels from beginning thing work, I used ScrollX * -1. The pixels from beginning thing is not exact but close to being exact.
