Worm Path

A grid puzzle about pushing blocks out of your own way. The worm moves one tile at a time toward an exit that is always behind something, and the blocks it shoves are the only tools in the game — there are no keys, switches or enemies. What makes it work is that the worm occupies the tile it came from: push a block into the wrong gap and you have walled yourself in, which is a loss you usually notice three moves later. Restart is instant, and you will use it.
