SuperTux/supertux

SuperTux is a free and open-source side-scrolling platformer game built with C++ that draws inspiration from the classic Super Mario Bros series.

The project addresses the desire for a community-driven, moddable platformer by implementing a complete game engine using SDL and OpenGL. Players control Tux the penguin through levels filled with enemies and obstacles, collecting items and reaching goal areas. The engine supports custom level design through accessible editing tools, allowing the community to create and share new content beyond the bundled campaigns.

SuperTux suits developers and players interested in contributing to an open-source game project or learning how a platformer engine works. The codebase is written in C++ and uses SDL3 and OpenGL for rendering, making it accessible to those familiar with these libraries. The project welcomes contributions ranging from level design to engine improvements, though potential contributors should understand that this is a game rather than a development tool or library to integrate elsewhere.

Development activity shows consistent engagement with the codebase through regular commits addressing bugs and features. The project maintains active issue tracking with responses to community reports. Pull requests receive review and integration, indicating ongoing maintenance rather than dormancy. The maintainers respond to discussions about the project's direction and technical decisions, suggesting sustained stewardship of the codebase.
