Ar Tonelico Qoga : Knell of Ar Ciel [BLES01102]

Save game works now (only 1 save slot, though).

As for crashes I guess it should be tested in somewhat long play, at least several hours, cannot perform it with my low-end CPU (playing like this is a sort of torture).

Also, from what I see, there are much less graphic glitches with Vulkan, but FPS is greatly also lower.

Maybe leave the game running for an hour or two and see if it crashes/hangs.

I played it about half an hour, then about an hour in background and it neither crushed nor looped.

BTW, not actually playable via keyboard right now, one of crucial game mechanics (purging) requires shaking gamepad to be activated. I could not find such an option in the pad settings xD
