The one thing that this game lacks, is the one thing that it truly needed.

I've been playing Japanese RPG's for most, if not all of my life. The one thing that i've come to expect, in any game (RPG or otherwise), from the past 5 or so years. Is an "auto save" feature. I really love this game. And, it's one of the best DS games, that I have played, so far. But, imagine my dismay, when I complete 2 of the worlds, just to be beaten by one lousy monster (not even a boss), and I lose over 7 hours of progress. Yes, I should have been saving constantly. Yes, I should have tried to flee from the fight. But, in the heat of the moment, and being so focused on progressing in the game, I forgot. The one thing I do enjoy, about the save function in this game, is that you can save anywhere. I just wish, that at the end of a planet, or even at the beginning of a planet, you would either be...
a) asked to save your progress.
or...
b) the game would save your progress for you.
I'm really hoping for a sequel to this, in some way, shape or form.
Maybe "Magical Starsign" for Wii...
But, I digress.
If you're looking for a great, funny, compelling, time-waster of a Japanese RPG.
Then, I think that "Magical Starsign" might be up your alley.
(Saving issues, aside)
