I got it running and the music is playing. This is as far as I managed to get. No response from keyboard, mouse or joystick but the window functioned without crashing. I hope this helps.

You did install the AUR package?
That’s strange, did you reach the main menu or is it broken right away?
To be honest I’m confused as I tested the AUR package on Saturday on a Arch machine using Wayland and plasma and it loaded fine.
So either something is different on your machine or the update broke something. As I do lack a Arch system where the game does run native on diagnostic is a hard. I have to ask a friend of mine to use his rig once again.
Thank you for testing it out.
That’s interesting, just did start on Arch and got the same issue.
I did the same on Windows and it’s fine, I might have an idea what could cause this.

Well … that might be an issue … :D

Yep, thank you very much, I will make a hotfix for that issue.
I will update the AUR, version 0.17.2 will work once again.

To explain this more into detail. Version 17 was a huge refactoring of the original code. Beside restructuring the whole codebase making the ui more simple was the main focus. Seems like I did not test that exact change on Arch Linux. Version 0.16.0 and 0.17.2 should work fine, all versions in between will be broken.
