You are the shepherd in charge of taking the sheep to their pens.
But the sheep (the white sheep-like shapes) are terrified of you, and run away the moment they see you! You can use the crates and walls to help you control them, and guide them to their pens. This is a challenging puzzle game, where you will have to think ahead and carefully weight every move.

12 levels. The last level is truly epic, and if you can finish it, buy yourself a beer because you deserve it.

Use the arrows to move and push the crates. At any moment in the game, you can type R to restart the level, and Z to undo a move.
