Arrow keys or WASD keys to move. Press the zero key to go into editor mode. you can remove the annoying level store if you go into the code. In editor mode, press the E key to use the eyedropper tool. In editor mode you can use the 1, 2, 3, and 4 keys to change the block type. sorry the coins or the mystery blocks don't work.
