Oh... Linux. That's additional work, and we're not yet sure how many players need this platform. I think we'll look into this matter in the near future.
Fair enough. I forget, is this a Ren'Py game? I was under the impression due to a couple other Ren'Py games that it was just another build target and would generate a .sh alongside the .exe. I am mostly able to get it to work through Proton though, so if it's not a priority no worries. I can still manage the versions through Itch and play it via Steam. If there is interest though I'd be grateful!
