Right Arrow to move right. Left arrow to move left. Up arrow to move up. Down arrow to move down. Don't touch the black! If you do, you'll be sent back to the start of the level. Reach the blue to move on to the next round!
Credit to @Dorie88 for the scripts! There are some bugs after round 3. I'll start working on the anti-bug version. Report to me any bugs BEFORE round 3. ^_^ (The Medium Level is actually pretty hard.)
