The mission one is fairly easy and simple, but it gets a little bit harder on level 2. There you will have to steer between big obstacles, such as floating icebergs and big bulky whales. Your job is to suck in as many fishes as required, so you can feed the starving penguins.

The third and the final mission is unbeatable, I believe. On this level you are shooting at the sea lions, which are penguins predators. You are not actually killing them as you use tranquilizer darts, but it's so hard to hit them as they move rapidly in a zig zag patterns. To make things even harder, you loose points for misses and you also loose points for not shooting. Basically you have a lot more chance to loose point than to gain one, making this level practically impossible.
