The Lost Vikings

In the game, the three Vikings get kidnapped by Tomator, emperor of the alien Croutonian empire, for an inter-galactic zoo and become lost in various periods of time. After escaping through the airlock of the spaceship, they must traverse various bizarre locations to find their way home.
Character abilities

All three Vikings (Erik, Baleog and Olaf) have three health points which they can lose by getting hurt by enemies or by falling from great heights, and the ability to carry and use items, mainly keys, bombs, and food (which restore health points). Each of the Vikings has a unique set of abilities:

Erik can run faster than the other two, can jump, and can bash through some walls (and enemies) with his helmet.
Baleog can kill enemies with his sword, or from a distance with his bow (and a "life-time supply of arrows"). The bow can also be used to hit switches from a distance.
Olaf can block enemies and their projectiles with his shield, and use his shield as a hang glider. Olaf's shield can also be used as a stepping stone for Erik to enable him to reach higher ground, which would not be possible without the shield.
