I will say the game is quite fun, even though a lot of the mechanic are a bit confusing, like what does the fury do? is the lucky find a boost on Sapphires or coins? What is the use for region mastery? and I have been playing it for half an hour just to find there's a time training page, class select, and prestige in the menu (normally people would suspect that is for game setting and not part of the content)
Also there are some suggestion that might improve the game--
remove the battle start button, it's a turn based combat that is fully manual, there's no reason for that button to exist in the first place (not to mention the hotkey is different than anyone else, which is a bit clunky to use, or at least make it only applied when switch region, so the player don't need to click it every time a battle is over)
better tutorial, or at least give the player a journal or additional information to know what some of the upgrades or buttons is supposed to do (like counterattack and brace, there's a lot of misses so it's hard to tell, and sometimes brace can also deal damage which makes me wonder does the character has a base counterattack chance or that's just a bug?)
more pup ups for achievement and quest completion, part of the reason I never checked if there are more pages to find is the lack of requirement, if the whole screen is containing everything I already and needed to know, then I wouldn't have the need to search for anything additional.
