GOOD NEWS EVERYBODY!
We found the reason why the Steam Deck refused to save. It took only 5 hours of our life!
The Steam Deck will now save the game correctly. We also added saving when the steam overlay opens.
On top of that: We now have a shiny new "exit game" button! That button will also save the game before exiting.
On Windows nothing is changed; everything worked before. So this is only relevant for Steam Deck users :)
Next up, a global solution for getting stuck in the environment.
Thanks and have fun on the go!
