I’ve switched between Plasma, Cosmic, Sway, and Hyprland without any conflicts. For the Plasma 5->6 transition it did change my config in a way that broke Plasma 5 when I rolled back, so problems are possible.

Basically your mileage may vary.

Great game but you need to go in with the expectation of a Devil May Cry-like and not a traditional Final Fantasy. If that doesn’t sound like fun, this should probably be a skip.
