Well, there isn't a Linux version, but it just runs perfectly with proton.

Runs very nicely in Proton.

I did have it crashing after just a few minutes of play. If this happens to you as well, you'll need to follow the instructions at https://github.com/zfigura/wine/blob/esync/README.esync to increase the file descriptor limit (this is technically a security feature, read the whole page and understand what you're doing)
