Alright, I checked and it does! Sweet! Although some note mentioning that would be helpful 🙂
I also updated Wine in my system from 4.0 to 5.0 and it works with Wine as well.
It is mentioned when you download it (under the "Download and install instructions from Labbed" section) and also on my website download page (http://labbed.net/software/labchirp/). However, it should probably be mentioned on the itch.io page as well! And perhaps in the manual.
I did not know it works with Wine! I've tried it before (several years ago) and it didn't work, which is why I tell people to use Mono. I will give it another try with the newest version and see how it works. Thanks for letting me know!
Good luck with your future game projects! And have a nice day!
It just occured to me that you could also make a 'start.sh' sort of bash script that would simply execute 'mono LabChirp.exe'.
Then mark it as Linux executable in the manifest so the itch client app can start it for the user, as long as Mono is installed.
