How to play
- Tap a cell to toggle it and its four orthogonal neighbors (up / down / left / right).
- The board is always solvable — it's scrambled from a solved grid, so a path to all-off always exists.
- Race your own best move count per size, or chase par for a perfect solve.
- Keyboard: ←↑↓→ to move, Space / Enter to press, N new, H hint.
