To see the code, click the See Inside button. Left arrow - left Right arrow - right Up arrow - Jump The trick to a scrolling game is that the background moves when you push the arrow keys. You need to make it so if you want to go left, you push the right arrow. If you want to go right, you push the left arrow. To make your character appear like it's jumping, the background has to go down when the jump button is pushed.
This was very easy to make, and it took less than 30 minutes. If you wanted to make a longer game, you would have to make multiple background sprites spaced apart evenly, each one containing the same code. As you can see, If you go to the edge of the background sprite and jump, It messes up. Don't do that! All Sprites are made by Me, and me only. That's also why they all suck =D.
