Question wasn't aimed at me but I would like to help out.
I would say Strange Journey is one of the better RPG's on the DS, it had a very good atmosphere and the gameplay was solid if, yeah, a little repetitive when you get further in. I frankly didn't have the patience some people had to navigate some of the more extremely difficult dungeons, so I didn't finish the game, unlike every other SMT game I played.
As for saving, there are allocated save points in the dungeons, but I don't think they are as often as what people are used to on a handheld. Though they are quite centrally located and easy to get to once you know where it is.
