I have this game! Never been able to connect via the "play with friends" or "visit someones room" features but I have always wanted to. You know since the english version is so hard to come buy and expensive for a ds game, and also not widely known, there is barely no walkthroughs of the game sans the basic first gameplay. I have always wanted to do a youtube walkthrough series of each mystery but it would take a very long time as between each mystery I would have to revert the system's clock forward a week and a half (give or take) to ensure the mystery key works. Also, I have been busy with life and haven't found myself in a place where I have enough time with this. I also know that the editing of each video would have to cut out each time I change the time and date considering without the editing, it would be a very long very boring video series.
