WASD to move and press 0 for the level editor. Press P if the level editor is open to open collision pins and then 1 to set them and x to delete them. You can build by clicking the level editor and clicking then on the level. If you want different layers press 1 2 or 3 for them. 1 and 2 are the same thing but if you use three then it is a layer above you so you can't touch it and you won't see yourself.
