Vibe coded a native Linux launcher for OctoWoW since I wanted a cleaner alternative to the install process through Steam. It runs the client through a self-managed Proton prefix, so no manual Steam shortcut needed.
Not sure if this is useful to anyone else, but here it is if so. If you use it and run into any issues or have suggestions, leave them below and I'll get to them as soon as possible.
