I don't like the fact that enemies have such high chances to inflict debuffs on you,especially if they are sleep and silence,but that doesn't mean that only they need tweaking since when you fight a lot of enemies in can be pretty overwhelming,like what's the point of having skills that remove status effects if the next turn i'm debuffed again? The characters don't even go one after another in terms of turns,making this even harder.
The fighting system definetely needs tweaking.
Haven't seen my characters able to unlock any new skills despite "learn skills" being an option.You could add skills that grant immunities to states if you would consider so.
The mp cost color is so dark,i bet you could find something better.
