I think the audio was mixed nicely, and the gameplay was pretty addictive! I think more varied sheep behavior would help the game feel more, "out-of-control," instead of just relying on a hard-set game-over after so many levels. By the time I got to level 10, the sheep were moving too fast away from me that by the time I caught 1, 2 more spawned, which felt less like something I could control with skill and more like just the game telling me it was time to be done. The sleeping mechanic was an interesting idea to implement, I think you could do something really cool with that if there was some additional consequence that wasn't just, "more sheep spawn." Overall, good work!
