Thanks, yeah adding Ralsei's maps would be cool, but there's a bunch of other stuff I want to do first, Chapter 3&4 maps being the next one, so it won't be for quite a while.
Oh, does it not automatically switch to xbox controller prompts (which is basically the same as steam deck buttons but it's got colours lol) on steam deck? I don't have one so I can't test it. If it doesn't, you can set it to show xbox prompts in the settings (talk to swatch)
Or if you just mean special images for steam deck specifically, maybe eventually, but for now xbox works well enough so it's lower priority than a bunch of other things
