Polarity Dock: pull the right shape home, in order

A real-time sorting arcade. Shapes drift in; your field either PULLS or PUSHES them, and the dock only accepts the shape it asks for, in the order of the queue. Wrong shapes cost strikes, mines stun you, and 13 loose shapes overloads the board. Rising levels, a moving dock, streak multipliers. Keyboard (arrows/WASD, Space, P) and touch (drag to steer, tap to flip).
