For the linux users to play: Runs perfectly with 'umu-launcher'.
1. Get umu-launcher (and let it download ProtonUMU)
2. Do in terminal `umu-run SALVOR\ DEEP` (better to let it auto complete the .exe file's name.)
Yes, you download windows version and this tutorial is almost-universal.
Decided to mention it if some linux-newbie might need it and was struggling with wine-tricks.
Also Delusria I guess you can mention in downloads "For linux just use umu-launcher on .exe" to have it available on platforms.
Please take care of yourself reader, yes?
