SuperTux is a jump'n'run game with strong inspiration from the Super Mario Bros. games for the various Nintendo platforms.

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.

For major platforms, stable releases are built and available for download from supertux.org or alternatively directly from GitHub. You should be able to install these using default tools provided by your platform. On macOS, when Gatekeeper is enabled (default) it will refuse to open SuperTux. This is due to the lack of a signature on the application. If you wish to open SuperTux anyway without disabling the Gatekeeper feature entirely, you can open the application from the context menu (control click on the icon). macOS will then remember your choice the next time.

Important documentation for SuperTux is contained in multiple files. Please see them:

• INSTALL.md - Requirements, compiling and installing.
• README.md - This file
• NEWS.md - Changes since the previous versions of SuperTux.
• LICENSE.txt - The GNU General Public License, under whose terms SuperTux is licensed. (Most of the data subdirectory is also licensed under CC-by-SA)
• data/credits.stxt - Credits for people that contributed to the creation of SuperTux. (You can view these in the game menu as well.)

Both keyboards and joysticks/gamepads are supported. You can change the controls via the Options menu. Basically, the only keys you will need to use in-game are to do the following actions: jump, duck, right, left, action and 'P' to pause/unpause the game. There isn't much to tell about the first few, but the "action" key allows you to pick up objects and use any powerup you got. For instance, with the fire flower, you can shoot fireballs, or with the ice flower fire ice pellets.

Other useful keys include the Esc key, which is used to go to the menu or to go up a level in the menu. The menu can be navigated using the arrow keys or the mouse.

In the worldmap, the arrow keys are used to navigate and Enter to enter the current level.

• Discord: Also, you can join our Discord server to get in touch with us.

As of now, with the release of SuperTux 0.6.3 (December 2021), the Forest World is almost finished, since the ghost forest section has been included. However, some levels, especially the Ghostree Level, are considered to be placeholders, because for the next version (0.7.0) a great overhaul is planned with new features like reworked boss fights, graphics, and worlds.
