Crate Push

Goal

Solve 5 Sokoban levels: push every crate (C) onto a target (T). A level is done when all targets are covered, then the next loads; solve all 5 to finish.

Scoring

Total moves across all levels — fewer is better.

Rules

Move up/down/left/right. You push a crate by walking into it; a crate only moves if the cell beyond it is empty floor or a target. You cannot pull. You can 'undo' the last move or 'reset' the current level (useful if a crate is pushed into an unsolvable corner). There is no time limit and no lose state.
