Use the arrows to move the ball. All levels have been tested by me and tips:you can wall jump, lava hurts, get to the blue ball to move to the next level. Sometimes the spawning glitches so just click the green flag again until it works. Don't worry, that is only on the first level.
Thanks djpro for the ball script when I tried to do it it failed so I just remixed it. I will always be adding new and harder levels! Please love this I've been trying to make a platformer for soooooooooooooooo long but I couldn't do the scripts correctly but now it is here.
