Instructions:
This game is based on Duck Hunt for the Nintendo gaming console.
The objective is to shoot all the flying "Drews" (birds with hats)
and progress through 10 levels without dying.
Avoid shooting the "Hulls" (large penguins) as they will cost you a health point.
There are many power-ups that appear randomly on the screen.
The bullet power-up gives you extra bullets to start with for all future levels.
The mushroom/life power-up gives you an extra health point.
