There are currently 22 levels. Use the A and D keys. If you hit the side of a platform you either elevate down or up. Click R to restart the level you're on if you get stuck. If you touch the red then you restart the level you're on. Go through the green portal to get to the next level. Click v to show the variables.
I look at this awesome game by MicahJ3482 and I wanted flying in it, I am also a beginner at Scratch lol.
