I'm looking at the DS version. I'm sure the screen rotates, but that just adds an unnecessary element to the game... the camera. Can you imagine playing Dungeon Explorer and having to worry about the camera angle at the same time just so it can be in 3D? I think the graphics could be a lot more lush and colorful, but since it is using 3D textures the visuals take a hit. Compare Astal on the Saturn to, say, Tomb Raider on the same system (or the PS1, it doesn't matter). 2D graphics will always be more lush and colorful when the 3D hardware is that weak.
