Yes, but you have to type/copy those lines individually into the terminal every single time you want to start the game, is there a way to not have to do it every time?
same on Debian. game uses steam protection to run. instead of looking for a solution to link that steamAPI file you'd better ask why it happened on DRM free storefront. I just sent error report, hopefully itch support can review this game and will ensure we don't need to dance around steam DRM to run this game.
