How to play
A slab slides back and forth at the top of the tower. Drop it so it overlaps the slab below. Any part that hangs over the edge is cut away, so the tower gets narrower with every mistake. Line up a drop perfectly and you keep the full width, plus a small bonus. The slab speeds up as you climb. The run ends when there is nothing left to land on.
