How to play

You are the keeper. Shove every crate onto a glowing pad. Crates only ever slide one square, and you cannot pull - one shove too many and you may wall a crate in. Undo is not cheating.

Keys - arrows or WASD walk and shove
Touch - swipe the board, or tap a square next to the keeper

Stuck? Watch it solve itself

Every level is generated already proven solvable. The solver replays that proof: BFS on small boards, A* with a distance heuristic on big ones.
