Hey, I just tried installing this from itch.io’s launcher on linux, and it doesn’t recognizes any downloads for linux, so it doesn’t give me any options. Maybe all that is missing is clicking the “Linux” icon beside the executable, like this:
Ah, I think you may be right. I've enabled that checkbox for the Windows and Linux builds, so let me know if it still doesn't appear for you. I wasn't aware of the launcher, so I've not tried using it before, but I guess I'll look into it. If the launcher still doesn't work, you should be able to download it in a web browser.
