SuperTux 2 is free software, a classic style 2D jump and run game inspired by the Nintendo Super Mario series. It was originally created by Bill Kendrick and is currently maintained by the SuperTux Development Team.
Instead of Mario, the hero in this game is Tux, the mascot of the Linux kernel, albeit the game's only reference to Linux. Many of the in-game graphics were created by Ingo Ruhnke, creator of Pingus.
