Jamul
The game ran okay for me, high speed, lots of sheep plowing by (not broken speed like I've seen other people mention though - it was quite reasonable). Not much of a game though... Even though all the sprites face sideways, I think it still would've been a much better game if you shot upward at the sheep coming towards you out of the screen. That way at least, you would know what's coming. As it is, very little clue when or where they are.
Funny that the guy's walk animation includes firing his gun, and he has no firing animation!
Plenty of destruction, no construction, and a whole pile of sheep.
Some bugs with regard to where you can walk (I went up a hill, hit the end, presumably the end of the world, then could only get halfway back down the hill).
