This is a parody made out of the game duck hunt.
The game is very similar to the original duck hunt for nes: Shoot the required targets to progress to the next level!

Here you use your mouse to shoot the targets instead of using a Nes/famicom Gun Each level requires certien numbers of targets to be shot.
Shoot these number of the required targets and you move to the next level.

Game itself is very simple, and similar to the original duck hunt:
Shoot the eagles before they fly away out of the screen.

Remember! For each target segment you have only 3 bullets! So use them accurate!
