In Haystax your job is to get those pesky black sheep to stop wandering off and getting themselves stuck on top of those precarious haystacks. The farmer will be the one kicking the white sheep out to topple the black sheep over. Use the mouse to adjust your trajectory and the power with which you'll give the sheep the boot. You don't have to aim for the sheep; most of the time you just have to knock over the haystack they are on, or knock over something in front that will topple them over. Every level gets a bit more intricate and a lot more fun in Haystax.
