So issues for the game:
Overdrive isn't at all useful. I do realize I was playing on easy mode, but even so, it takes too long to get to your overdrive and many enemies are likely going to be dead by then.
You can walk out the maps in some places such as the forest and other passability/layering issues.
You can't return to town except between levels.
Why do we trust this Syran guy?
So we start off with the brother dead, then later some guy claims to be the brother and that you lost your memories... and you just believe him?
Elemental weaknesses are not intuitive. Basically everything is weak to electricity. What isn't weak to electricity is basically weak to fire with the exception of one area with ice weakness. Thing is, even earth elemental and lightning element enemies seem weak to lightning. Nothing seems weak to Earth or Light. The Earth skill is especially useless as it doesn't seem to scale. Make it deal like 10~20 damage per level or something.
Some skills that say they do 20 damage don't.
Boost doesn't seem to help your non-skill damage or doesn't help it much even with 3 boosts.
Weird art changes with the character enemies.
Check spelling/grammar.
