Linux version does NOT work on Steam Deck; launching the executible causes the error "execvp: Exec format error."
The Windows version can launch on Steam Deck, ONLY if you edit the launch options to "Force the use of a specific Compatability tool" and set it to "Proton: Experimental." However, there is no graphics and the game was stuck on a blank white screen.
Also, both downloads have dozens of hidden TEMP files from the Mac OS. Files like .ds_store, and hidden backups of files in the _MACOSX folder. These can only be seen if you enable "show hidden files" on your system, but they add a lot of the file size. As someone who has a Mac for my work and transfers between it and my PC, I know how much of a pain it is to manually remove those, but it's something that should be fixed.
