I managed to install the game using Lutris, and it boots up, but I keep getting error messages stating that it can't find various sound files. I can't even play muted because it keeps popping up error messages stating that it can't find various files. How can I fix this?

download the music zip and copy the music folder into the game folder

I should have mentioned that I did that. The sound files in question seem to be in the sound folder that's already there. It looks like SteamOS can't find the files, possibly because its directory works differently, but I don't know enough about Linux to troubleshoot the problem.

that said, try using Bottles instead of Lutris.

also, maybe your download is corrupted.

if that doesn't work use bottles also

oh and if the game is low FPS, change the resolution to anything other than "fullscreen" and it should be locked 60 then
