I'm currently unable to play the game since the hotfixes seem to have broken Proton compatibility for the time being, but I've got about 36 hours in with the Steam Controller so far.
It would be nice to have proper Steam Input API support, but I don't expect that to happen. What I would like is for the game to play nicely with mixed gamepad + mouse + shortcut key inputs. So not rapidly switching glyphs when I use mouse aiming, playing smoothly with mixed joystick and mouse aiming, menus still navigating with the dpad independent of the current mouse position so that if I have gyro going off it's not messing that up.
For my scheme, I would like to be able to just always have mouse aimin
