User blog comment:Facto/Fangame Collaboration Proposal (PROJECT OBSERVER)/@comment-13680562-20141212102602/@comment-13680562-20141213014927

That's much better but still not so fit which it links with the dream world that Japanese said in Yume Nikki and the title of Sword Art Online ED.

So I suggest you can change slightly to ISEKAI NIKKI (Diary of Another World) or rename to other english names such as Dream Dimension etc which fit with an english collaboration.
