The game is now playable on Steam Deck with changes to the launch option. Thank you to the other report here!
radeonsi_zerovram=true %command%
Changed in-game control settings
The game support input changes via in-game settings, needs to make changes in the options menu and you are good to go.
radeonsi_zerovram=true %command%
The game does allow controller input, but it needs to be mapped via an in game menu first. I made a layout that maps the arrow keys and enter to the right stick, and used that to set up the rest of the controls properly.
Credits to https://steamcommunity.com/id/Wantija for first posting the launch options fix!
Title screen corrupted and I was not able to proceed past it.
Both GE-Proton and Forced Experimental get the game to launch, but graphics are heavily corrupted and the game accepts no controller input.
Technically an improvement over older versions?
Crash on launch
Throws a nasty dot net string or number format exception on start-up. Seems to be a wine-mono issue, but Proton has those dependencies. I also tried running the executable from wine itself with mono installed, produced the same issue.
Errors out when starting
Crashes on launch
Tried all versions of Proton, including Proton-5.6-GE-2
