The object of this game is to keep the mutant penguins from reaching the "doom scale," and to help the "good" penguins reach it. This game can be a bit confusing when you're first trying to figure out how to get your weapon, how to power up your weapon, and so on. But once you get the hang of it, you'll be zooming through the game in no time. The graphics are nice and colorful, but the sound is a problem. It's not that the sound is bad, it's just that there barely even is any sound. There is no music, and very few sound effects. The control, however, is solid. The game isn't very challenging, with 20 short levels. Chances are you'll breeze through the game within a couple days. It is moderately fun while it lasts, though.
