You can be as some kind of God in this nice game.
With an angel (your manager or something else, too), you build up the city and seal some demon's entrances. That way, the village gives you some useful item (it can be a magic, or more HP, etc.) for the next stages. So, it's a combination of action, RPG and strategy game, which makes this game unique.
The gameplay is good, the difficult is right, but sometimes the bosses are difficult to kill, anyway, with some of effort you can solve it.
The sound is just 0k, and the effects are typical from a Enix game (if you've played other Enix games, maybe you will know what I'm talking about).
This one game does not excel in any aspect, but if you play it surely it will be left engraving in your memory.
