I finally learned how to upload a Linux build of my game onto steam.
AI Stories can now be played on Linux mint 22.1. in a native way.
I honestly don’t know if it also plays well on other Linux distributions. It is not a flat pack build.
If you are facing compatibility issues on Linux, you can right click on the game in your steam library, go to properties, go to compatibility, activate “ Force the use of a specific Steam Play compatibility tool “ and then choose a runtime layer that works best for you.
I chose the Steam Linux Runtime 3.0 ( sniper ) to be the default runtime for Linux.
