Over the weekend, I tried Tesla Effect which is part of a series of the Tex Murphy games on Ubuntu 18.04 using Steam Play. It works with no problems. You would think that it is native to Linux. This made me happy. Almost all the old game series were moved to Linux except Overseer. As of this writing, Overseer still does not work on Proton. If you are interested in Tesla Effect. I suggest to start with the older games in the series like Under a Killing Moon to fully enjoy the narrative.
