Linux Player here...You put out the wrong file type. Linux programs files are ShellScript (.sh) not whatever that is (.X86_64) please fix. I cannot install/play as it is now.
For further Clarification, Itch allows .zip files, and they will be automatically installed/extracted upon download via the app. Most publishers on here host the .zip for both pc and linux as one .zip file containing both the .sh and .exe launchers. I do appreciate you figured out how to use the compatibility toggle for file uploads, though I should mention you can click multiple of those boxes per upload.
Thank you so much for letting us know — and really sorry for the complications with the Linux version.
We appreciate your patience and your clear explanation. We’re already working on fixing it so you can play without issues as soon as possible.
Thanks again for your support and for helping us improve!
