I liked this one, great concepts, excellent graphics, sounds and music, and good controls too! As others have mentioned, the primary issue is the sheep getting stuck up against the walls with no way to move them. This was addressed nicely in the 2nd level, with the hay barriers, allowing the player to get on the other side of a barrier sheep are up against, to get them away from it, but sadly, the rest of the levels didn't really offer similar options, so usually most of the sheep got stuck up against the level boundaries or objects that the player can't climb on. Still, great entry, lots of fun, and really charming!
