What is osu?

CrystalGovernor/OSU is a C++ project targeting players of osu!, a free-to-play rhythm game from ppy. Based on its description, it is billed as a visual assistant and performance analysis toolkit for Windows, published in June 2026. The repository's listed topics provide the main clues about what it does, since the README itself contains only a banner image with no written documentation. The topics reference aim assistance (tools that help guide cursor movement toward hit targets), an osu! bot, a "freedom hack," timewarp (a technique that slows down song playback speed during gameplay without the game detecting it), and dedicated tools for osu!mania, one of the game's four main play modes. Because there is no README text, build instructions, or usage guide, it is not possible to verify how these features are implemented or how to set the project up. The C++ codebase would typically interact with a running game process using Windows system calls, but nothing here confirms the specifics. Prospective users should be aware that tools described as aim assistants, bots, and timewarp utilities may violate osu!'s Terms of Service. The game actively bans accounts using third-party software that automates or manipulates gameplay. This repository does not discuss that risk or provide any compliance guidance. No license is specified in the repository, so the legal terms for using or modifying the code are not clear.
