Go play the original, cause it's better: https://scratch.mit.edu/projects/103676705 Press 'Q' to make a platform. Press 'E' to delete them Press 'Space' to go speed. It can go through brown walls but silver still kills you. Press 'Down Arrow' to teleport.
@key01134 did pretty much all the code. This took me pretty short. So go play the original version.
