But not only that you can only push your crates about, you cannot pull them this means that you don't get a second chance, if, say, you've pushed a crate wrongly and there's no space to push it back to its starting position. It's easier said than done, because each level, each warehouse floor, as it were, has some other things in there that can't be moves, thus, you are space constricted. Sokoban is an original puzle game, that can be resumed as a challenge in which you try to push the crates in a warehouse in their pre-requisite positions. Push the crates into their designated spots!
