5th time playing this....
... still no idea how to get the ending "D". I've let my hope dwindle until I only saw the ghosts, but after I did that (and collected their memorabilia), the temple door didn't open. Perhaps, seeing Chloe was my downfall.
I think, in a way, it's kind of punishing to players who could run into both their dead bodies and ghosts at the same time (and closes ending "C" and "D" routes, I presume). I admit I didn't give much thought about how to kill Chloe to get her ghost, but not sure if that's a good idea, or that is even in this game.
Though it's taken down from the front page, people really should look at this kind of game closely. It shows how being hopeful or being miserable could be one and the same when you are in certain situation like this. For that reason, this deserves 10/10.
To those who are complaining about no map in this game, don't know what to say to you. It's not that hard to memorize certain locations if you try hard enough. I mean, I played each playthrough over five days, and didn't miss anything.
