What was the best head scratcher you came across while playing on your DS. Did you manage to solve it? or did you leave the game alone hoping to come back to it later? I am going to say Zelda Phantom Hourglass for me. I am not going to say how to solve it but.. I remember I had to find the Sun Key. It said I had to align the Southwestern Sea Charts so a hole, or rift in time would appear. I must admit, Nintendo do have some devious puzzles. Especially the Metroid and Zelda games. I was amazed at how good a puzzle it was. Anyone care to share there thoughts?
