Ah Remember11. One of the best psychological thrillers out there, and also one of those games that will just severely tick you off (play it and you'll know why). I still remember how excited I was after playing Ever17 and then watching the Remember11 OP. It was the first game I felt was actually worth braving through with a dictionary back when I knew no Japanese at all, and it was well worth the effort....
I think I must have spent a week after trying to figure everything out, but to this day...
Still no luck
