Boxed In

Play:

Full screen Touch: Drag a finger across the board to move the wall-placement paddle in real time, then lift to place the wall — confirmed by testing, not just by reading the code. Tap the on-screen "Swap Direction" button to change which way the next wall grows, standing in for a desktop right-click. · Keyboard: Mouse: move to position the paddle, left-click to place a wall, right-click to swap direction. Arrow keys and P (pause) also work per the source.

About:

Two or more balls bounce around an otherwise empty board. Your only tool is a wall that grows from a point you choose toward both edges, sealing off whichever side ends up empty when it finishes — struck by a ball before it completes, it breaks and costs a life. Clear enough of the board to advance, with progressively less room to work with as it fills in. Rebuilt entirely from scratch under the MIT licence, not using any original assets.
