This is one of those projects that probably won't run well on the scratch website. A compiler such as Turbowarp is recommended. Controls: WASD to move cursor. E to change editing mode (off, tiles, pins, & doors). R to rotate a tile or door, or hold R to give pins a different color. SPACE to place a tile, pin, or door. Q to remove a tile, pin, or door. UP/DOWN ARROWS to change floor. LEFT/RIGHT ARROWS to rotate the screen while not editing. O to cycle the position of the main entrance while editing. P to save.
