installation and the game itself seem to work flawless with Lutris.

Out of the box or tweaking? Also which version did you choose in Lutris as you can use latest....but it updates often. It is good to note which version of wine etc and settings are used for future reference. Thanks!

it was out of the box without any changes. I am using lutris 0.5.9.1 and wine 7.1.
But now, with the lates game-update, it's not that stable anymore.
The game is closing it self from time to time without losing the latest save-game...

I realy hope this changes again with upcoming updates.

Indies used to almost always support Linux, but now there are all of these Windows-only indies cluttering up the scene. So sad.
