About the game

Wobbin the stork rides a slab that slides back and forth above the tower. Tap to drop it. Whatever hangs over the edge is chopped off, so the next slab is thinner. Line it up well and nothing is lost.

Drop it almost exactly on top for a PERFECT and keep your width. Three perfects in a row make the slab wider again. Miss the tower and the level is lost. Each level asks for more floors and a faster slab, and a second chance helps once per level.

Controls

Tap, click, Space or Enter drops the slab. Second chance retries the floor once per level. Keyboard: P pause, M sound.
