Hello! Thank you for the report.
Could you please let us know if this is the Free version or the Full version? (You don't need Steam to run this, but we'll debug it.) Thank you!
Hello! Thank you for your patience.
We've finished debugging this issue and uploaded a new Free Build for Linux. We hope it's working now!
Additionally, the game is still marked as early access as we're looking to add a few more features such as an image gallery and language localization. The final version will be the same like right now, a free version with 3 love interests and a full version with extra content.
Hello,
If the current free version is updated without renumbering, I'm afraid the issue is not solved.
From the log, even though the game itself from itch.io is not depends on Steam, but looks like it should write files on user's home directory? If so, this might be a problem. Seems like Tails does not grant programs to write on user's home directory for the security reason.
I didn't test on the another distributions, but as long as the game runs without errors on some major distributions like Fedora, Ubuntu, etc., this might not be a problem since Tails is not really designed for running such a thing.
Hope my opinion helps.
