I have a standalone installer for the game "Osmos",
OsmosInstaller_1.6.0.exe that is meant to be run on Windows. I would like to play the game on Ubuntu 20.04 through Steam, but I am not sure how to do it.
I tried adding the installer to my Steam library through the "Add a Game" dialog, but when I click "Play" nothing happens.
I also tried extracting the contents of the installer with Archive Manager, and adding the extracted
Osmos.exe to Steam in the same way, but clicking "Play" still doesn't do anything.
I realized that I forgot to force the use of Proton. I was able to run the installer in Steam. The installer then asked if I wanted to run the game and it ran. I am not sure how to run the game again though. I found the installed files in my
.steam/debian-installation/steamapps/compatdata/2621714962/pfx/drive_c/Program Files (x86)
But adding the .exe to Steam in the way mentioned above produces the same results.
