Thank f this game was in NanoReno otherwise I never would have found it again because I never remembered the title. I NEVER figured out how to get a decent ending. At least with Valentine, I definitely tried everything and I don't think I ever got a ending that was happy or explained anything. I think after a while I assumed there wasn't a way.
I feel like I remember there's a point where the game sends you to a YouTube video and maybe there's something you were supposed to do with that which I missed.
Oh and Aurora's whole chase was scary to me. Kind of like the "Something is coming" in Pokemon mystery dungeon. Less scary after you figure out nothing scary ever pops up no matter what you do.
(Actually, I'm pretty sure I found this game initially from NanoReno's page too)
