SuperTux is a classic 2D jump'n'run sidescroller game in a style similar to the original Super Mario games.
You play as the penguin Tux on dangerous journeys through sometimes difficult icy and snowy lands and later through a forest world.
Collect coins and powerups, stomp one of the many enemies, burn them with fire balls or freeze them with ice balls and try to run to the exit alive as you advance through each level. Some levels even have their own little unique surprises.
SuperTux features a main story and a large number of extra levels. If those aren't enough, even more level sets can be downloaded in-game as add-ons.
