I played this game on stream as part of a roulette of indie games. I ended up playing it for way longer than the normal 1hr I give for games. I can honestly say that this was a treat in quality for the 2hrs I got into it. I have only the few things to note.
-Controller function should be native. It's good you incorporated something with it to help with mapping the controller to work with it, but it may be better overall to just have the controller natively work with it.
-In the English version, there are moments in the intro/prologue movie where if you are in Windowed version, the words cut off on the edges but this does not happen in Fullscreen. I think this also happens with one or two text boxes during gameplay in Windowed vs Fullscreen.
-No other notes, the rest has been wonderful in regards to sound, graphics, UI and so on. Love the battle system and everything else so far! Definitely looking forward to playing more.
