That's unfortunate :( I only tested on Ubuntu myself so far. Update should be coming in the next few weeks hopefully once I've gotten around to fixing some other bugs and adding some things players have been asking for.
i found a way. vavle released an update for steam today. now it is possible to add every .exe file into steam and start it with proton. so i downloaded the windows version, added om101.exe into steam and forced it to start with proton 3.7-8. it works!
