Shepherding is very serious business. Sheep dogs are raised as very serious, work focused animals.... That's why they use magic boomerangs to help them push sheep around. 

Sheep dogs can use boomerangs... right?

Anyway, you goal is to gather the sheep together into one place. (If you are having trouble getting started try hitting two or more sheep at once) 

Controls:
W/A/S/D - move

space - throw boomerang

hold space - change the arc of the boomerang

shift or E - switch boomerang mode
