I tried running it under Linux with wine but it wouldn’t react to any inputs. Could you make a Linux build please?
It worked fine with Wine for me - did you try pressing X? That's the key that advances the into dialogue.
try running in wine virtual desktop, unity games usually refuse all input after you click off of them when run through wine. the command would be wine64 explorer.exe /desktop=WineDesktop,1920x1080 LostCall.exe
I ended up running it with Lutris + Proton and it worked fine
