Numbers to select color, click to place*. 'Z' to play, 'X' to build Arrows to scroll during build Arrows to move during play (Scroll automatically**) Hold space + 'N' will give you a save code for your level. Hold space + 'M' will allow you to enter a save code. Note that the larger your level is, the longer the codes will be! *Here are the colors: 0: Empty - White (Default) 1: Wall - Black 2: Lava - Red 3: Finish - Green 4: Bounce - Pink **The scroll will be on the 8th left, 8th right, 4th bottom, and 5th top, so try not to have platforming there in some advanced levels, as it can be annoying. Or ignore this.
