what is totf-multiplayer fr?

This project is a mod that adds multiplayer to Thrill of the Fight, a VR boxing game played on SteamVR headsets. It is not made or endorsed by the game's original developer, it is a fan project built on top of it by an outside developer. The author describes it as an early alpha, meaning it is still rough around the edges. The README is upfront that players should expect bugs, characters getting out of sync with each other, and occasional crashes, especially around getting the physics and punch hit detection to line up correctly between two people boxing against each other online. The author also notes that there is no official modding platform for this game to build on, which makes the work slower and harder than modding a game that officially supports mods with proper tools and documentation, so progress depends heavily on trial and error. To install it, a player needs to first set up MelonLoader, a separate tool used to load mods into Unity games, along with a specific supporting library called Steamworks.NET, which handles some of the communication the mod needs with Steam's own services. The mod file itself then gets placed into the game's Mods folder inside the game's install directory. Once installed, using it is simple: from the game's home menu you press a Multiplayer button and that is the whole interface, no extra configuration screens or settings to dig through. The project is open to outside contributors, with the usual GitHub workflow of forking the repository, creating a feature branch, committing changes, and opening a pull request. Anyone interested can also check the issues page for a list of known bugs and planned features to work on. It is released under the MIT license, and the README repeats more than once that it is a fan-made project with no official affiliation to the game's developer.
