## What it is
SuperTux is an open-source 2D jump'n'run sidescroller game inspired by Super Mario Bros, starring Tux the Linux mascot. It features story mode, community levels, an integrated level editor, and local multiplayer, built with C++, SDL, and OpenGL.

## Use cases
- play a free open-source platformer game
- play a Super Mario-style game on Linux
- create custom platformer levels with a level editor
- play a 2D sidescroller on Android or in the browser
- contribute levels or add-ons to a community game
- study the source code of a complete C++ game

## When to choose
- you want a free, cross-platform 2D platformer with no ads or purchases
- you want to build or share custom levels via an integrated editor
- you want a Mario-like game that runs natively on Linux
- you want a game whose full source is available under GPL

## When to avoid
- you want modern 3D graphics or AAA production values
- you need online multiplayer
- you want a game with official console releases or DRM storefront support
- you need a signed macOS application without Gatekeeper workarounds
