Well choco porter is nice for low leveled but that's all.
IMO, the only two major flaws of the game are dungeon musics since they only appear a few second then there no music at all when out of battle and the fact that the world is small and have poor usefulness once you reached endgame.
Other than that the game is great.

Oh and I forgot about latency, quick AOE can piss you off quite easily.
