POLYPOP

merge · bounce · clear

Drag back & release anywhere to fling the next shape.
Two matching shapes merge into the next one up: ▲ → ■ → ⬟ → ⬢ → … → octagon.
Two octagons POP, blasting nearby small shapes off the board.
Bank shots: every wall bounce before a merge multiplies its points.
Every few shots a stray shape drifts in. Don't let the board fill up.
