SuperTux

SuperTux is a side-scrolling platformer where Tux the penguin runs, jumps and stomps across icy islands to rescue his friend Penny. Slide down snowy slopes, swim through freezing water, bump question blocks for coins and power-ups, and bounce on snowballs and Mr. Iceblocks on the way to each boss. Pick up a fire or ice flower to throw fireballs and iceballs, an air flower to run faster, jump higher and glide, or an earth flower to turn into a stone that crashes through enemies. Two story worlds, hidden areas and bonus islands keep you exploring, and a level editor lets you build your own.
