i don't know what to do, but rely on luck for decide how far you can go in Aquapolis is not nice and quite unfair... rng is rng, you can be freaking unlucky and never seen pass the 3rd room in all your try.
get Aquapolis is already luck, then you must choose the right door for continue and another time you must be lucky to get the rare treasure room for get the best loot...

do i'm into a casino? or do i play FF14? not everyone love gamble, there it's way too big gamble!

personally i will be ok, with a reduction of the timer when you pick the wrong, door instead to simply.... you loose get out.
