And that's putting it nicely, I'm afraid. As someone has already pointed out, it's left-click to shoot. The gameplay is quite bland and repetitive. Also, this may be a bug, but several times I've tried playing this, I've fallen asleep regardless of whether the sheep touch me or not.
it's boring and short
i can't find something good to say about this accept from effort you need some improvement
this is incredibly repetitive and easy, you can just stay in the left side, vertically centered and mash the left mouse button and win about 70 % of the time, maybe add multiple, slow moving, high health, boss sheep that spawn more sheep or something.
