SuperTux

Classic 2D jump'n'run sidescroller featuring Tux the penguin. Run and jump through multiple worlds, fighting off enemies by jumping on them, bumping them from below or tossing objects at them, grabbing power-ups and other stuff on the way. Tux and Penny were out having a nice picnic on the ice fields of Antarctica. Suddenly, a creature jumped from behind an ice bush, there was a flash, and Tux fell asleep! When Tux wakes up, he finds that Penny is missing. Where she lay before now lies a letter: "Tux, my arch enemy! I have captured your beautiful Penny and have taken her to my fortress. The path to my fortress is littered with my minions. Give up on the thought of trying to reclaim her, you haven't got a chance!" - Nolok Tux looks and sees Nolok's fortress in the distance. Determined to save his beloved Penny, he begins his journey.
