I really appreciate you reporting these bugs, and I'm really sorry for your inconvenience. Unfortunately I have decided to pull Linux support. As far as I know, it was stable on Linux initially, with the exception that saving did not work. In my recent update I changed a lot, and it looks like it broke the game for some distros of Linux. I was faced with the decision of either rolling back the build for the Linux branch (which would mean saving would be broken again), spending more time and resources fixing the extremely numerous bugs I continue to have with Linux's many distros, or pulling support for Linux. Supporting Linux has proven to be more than I can afford to handle at the moment, and that's a mistake I'm deeply sorry for! I can arrange to send you a refund via paypal if you have a paypal. Let me know!
Thanks so much for being so understanding! I've finally managed to roll back the Linux build to the last working version on Steam, so hopefully it works as good as it ever did now. If you're not using Steam let me know and I can get you a link to download it seperately. I don't want to put it up on itch because then itch show as supporting Linux.
