I guess I don't get the concept. The box with the yellow circle (upper left) starts out at 1000 and the box with the duck (upper right) starts out with 6000. As you shoot, both go down. When the duck box hits 0, the game is over. If you spam click, the cannons no longer kill the birds and they become armed with badminton shuttlecocks and destroy the world (or something like that). That's all there is to it? Was this intended to be a (small) child's game? If so, nix the blood.
I didn't care for it because: 1)..birds are too easy. 2)..cannons can't handle big flocks. 3)..no upgrades. 4)..no instructions explaining how to set up cannons. 5)..that blue, yellow and red thing (umbrella?) just sits there and does nothing. What is it for? Decoration?
