Arrow keys to move. Press the s key to save a position and press the r key to teleport to it (If no position saved you will go to the start). Get to the end of the maze. This is the same maze as the first level from Super Paper Guy: Maze but in 3D. So it will be easier if you've already played it: scratch.mit.edu/projects/519790033 Enjoy.
I plan on putting in the other levels as well. But you probably won't see that in a loooong time. This isn't really 3d it's like I'm lying to you. In fact, I am. I love to. Also, very much of lag if you don't have a monster computer.
