I played the demo for a bit and noticed 2 things I'd like to see improved personally:
1) A better explanation of the action commands (mostly the block). Maybe do as Paper Mario did and play a short tutorial where players can practice the timing?
2) The menus to be flashier. Since you drew quite a bit of inspiration from Persona (5) and just with the graphics of the game, I think it'd make sense to show a little animation of some sorts play while in menus and maybe a bit more color?
The game looks and plays very well overall though, keep it up!
