It's a good game, but there is so much stuff to be improved.
encounters are too frequent every 2 1 second, theres no beastiary or anything that tells you what creatures drop what materials, yukidia is a very very hard boss considering his blind attack can make your characters attacks miss constantly, theres no potions that would do something for all party members at the same time, materials are pretty rare to come by, theres no reason why attacks should miss other then the blind effect.
if you improved on these things by updating the game after working on it, that would raise the rating up to a 5.
