Or, just if you like pretty colors. Some levels have more than one possible route, making the exit just a bit more difficult to find, but that's part of the challenge. It becomes apparent that some herders are just better than others, and some breeds of sheep are easier to herd than others, making for greater variety in game levels. Graphics are actually better than I expected. Good variety of colors and details.
Game plays very smoothly and animations are fluid.
Adorable sheep bleating sounds and cute music.
