example: cant cross a barrier in rivellon riftrun to Nemisis walk a coullpe of steps right riftrun back after the barrier. (like in zelda (snes version))
Although I like the idea, it might not be appreciated that much by everyone. Kindof reminds me of soulreaver, a game in which you could travel between two worlds, and you had to solve puzzles that way.
You had the material realm and the spiritual realm. Both of them looked pretty much alike, except in the spiritual realm time would stand still, and you could pass through certain objects, but you couldn't move anything around, or pick anything up. Or certain objects would appear only in the material realm and not in the spiritual realm.
Ofcourse it was an innovative idea, but the game gets a bit too hard for my taste.
