VVVVVV is the open-source release of an indie platformer game originally published in 2010, made available with its full source code for personal use and modification.
The game is a gravity-flipping platformer where the core mechanic involves reversing gravity to navigate through rooms filled with obstacles and hazards. Rather than jumping, the player toggles gravity up and down to move through carefully designed levels that require precise timing and spatial reasoning. The source code release allows players and developers to examine how the game was constructed, modify it for personal projects, or port it to different platforms.
The project suits anyone interested in studying game design and implementation, particularly the architecture of a successful indie title. The desktop version source code is available for compilation and personal use, with commercial distribution governed by the license terms. The codebase has been ported across multiple implementations, including versions in ActionScript, C++, and SDL2, reflecting different technical approaches to the same game design.
The project maintains active discussion around code and updates in a dedicated community channel. Multiple developers have contributed substantial work including a full C++ port, an SDL2 and Steamworks port, and ongoing maintenance. The codebase includes localization support across numerous languages maintained by dedicated translation teams, and continues to receive contributions from community members beyond the original creators.
