Build it high

Stack

Click, or press space, to drop the sliding slab. Whatever hangs over the edge falls off.

• Land it flush and the slab keeps its full width, plays a note, and the tower speeds up.
• Keep it up and the note climbs the scale, one step per flush drop.
• Reach the octave - 8 in a row - and the tower starts growing back, a little more with every one after it.
