TeamXbox played through the first dozen puzzles, and the controls are incredibly simple: You move a hovering alien saucer over fields, meadows and other terrain, which alarms the nearby sheep to run away. Using this new momentum, you guide the sheep over, under, around and through obstacles, directing them to the base of the mothership, where they're beamed aboard and kidnapped.
As you progress, you unlock new features. For instance, you become able to speed up the movement of your craft, at least for a short interval, by holding in the Left Trigger to boost the engine. Other unlocks include items that you can use in the Level Editor, which enables you to build new puzzles that can be shared with other players.
