The art style is super nice! The camera shake, pixel art, and overall feel for the game is really nice. I think the main thing its missing is something to really drive up the pace. Ignore my terrible suggestion, but I think it would be really amazing and funny if you could violently throw the sheep at mach 5 to bounce into the pen. Aside from that, all the enemies look really nice and I get anxious shooting them when my sheep are near. Great job!
