Qwak

The object of the game is to guide a green duck through eighty levels. Fruit and gems can be collected for points, and enemies are eliminated with projectile egg weapons. Progress through the game is earned by collecting gold and silver keys. There are a variety of power-ups also available, including 'chocolate egg' weapons and extra shots.

In addition to the normal-style levels, the challenge levels require the player to complete levels and collect all fruit within twenty seconds.

Upon completion of all eighty levels, the levels are looped.
