I was able to get the base game working on linux, but not ImPick. Start implauncher.exe with a recent version of proton, it runs fullscreen with no graphics issues I've seen (wine 10.19 had some window size and rendering order problems). You'll have to manually create the `data/ply` folder and copy character data into it, otherwise works great.
I wasn't able to get ImPick running under wine/proton, but it might work with an altered windows build, or linux build which has you launch the game yourself through steam/lutris/whatever and just manages character data.
Boring technical stuff:
ImPick.exe fails to start because of a problem loading the python314.dll. I'm able to run a very basic python 3.14 script with wine 10.19. PyInstaller uses upx if it's available on windows but disables it on linux, it's possible that running PyInstaller with --noupx or an older python version fixes things, but I haven't made a minimal PyInstaller program on windows with 3.14 to test.
Thanks for all your work on researching and preserving this!
