Few games are frustrating for the right reasons. Losing all your items and things because you made a mistake and solely your mistake, that is okay. Losing all your items and things cause you got unlucky, that is not okay. This game makes both things happen.
This game is simple, make it through the dungeons with limited items and no levels. Since you lose levels every time you clear a dungeon (At least I think so, I can't really remember). You have to plan accordingly, make sure you bring items with you.
This was a fun game. It had a decent story, the characters were likeable, and it was funny. I enjoyed it and was decently challenged. I'm hoping for another title in the series. It is very interesting and they have a lot to build on.
