Currently unplayable on Linux. I lags with most versions of Proton, Glorious Eggroll, and raw custom wine prefixes. I just found this game as of today, so I don't know if support was dropped in favor of gameplay features. I would request if it is dropped, that you probably remove the tags that says it supports Linux. Alternatively, if you have a binary that I am missing inside the provided ZIP file, then appending the updated binary in the ZIP would also be great.
