Used Proton Experimental flatpak community build 7.0-20221115
Just need to use the mouse controls for the launcher.
As previously stated, required mapping controls to a kb+mouse combo to work correctly
Launcher cannot be navigated with gamepad controls and requires use of mouse/keyboard/touchscreen/steam input configuration. Perfect otherwise.
Works just great!
It's perfect
Not found a single issue
(I have not tested using a gamepad)
Runs great, had no issues running it with an xbox one Controller.
Tested with proton experimental. Driver used for wireless game pad was xow The Dungeon rescue worked properly as well, have tested.
Current beta build works fine
There are a variety of different gamepad problems in the current live version that make gamepad use quite hard. The December 15 v1.0.2 public beta branch seems to resolve all of the issues for me when used with Steam Input support enabled (out of the box experience).
Everything else seems to work out of the box with the default Proton 5.13-4.
