Fantastic demo. Instant wishlist.
Small bit of feedback tho, scrolling up/down in the settings on touchpad moves the sliders, small bug. With all these nice settings a "restore default settings" button might be useful.
Fully supporting the controller would be fantastic. Currently, I can do almost everything with the controller (although some ergonomic details need improvement later) except for the skill menu; I can't see the upgrade information. A system like in Final Fantasy VII Remake, for assigning Materia, would be great. For example, pressing 'triangle: PS' or 'Y: Xbox' or 'X: Switch' (the physical button location is the same on three different controllers) would allow me to enter reading mode, and then use the home button to cancel/back to return to upgrade mode.
