thank you so much! We are happy you enjoyed the game:)
I think it might be related to how FMOD behaves in the browser. Could you try a different browser? So far I uploaded only Windows build, but I will make for other OS later too
Just tried in Chromium and it's better there, it only glitches a little while I move the camera. I wouldn't worry about it too much, it's probably only an issue in Linux.
