Just started to play, noticed I don’t have any sound. All other audio on my system works.
It’s a Linux Kubuntu 20.04 desktop system with headphones (USB cable). I tried restarting the app (launch via itch desktop app), and restart my systems’ plasmashell, all to no avail.
Looking into the games’ directory, I see the track names are capitalised and with spaces - do you refer to them as lower case, maybe? Windows gives more leeway than Linux on that matter.
Let me know if you prefer to handle that on some other place!
