Oh god, this game is amazing (and making me ~100% less productive this week) ;_;
Got Hanako's good ending on my first play, wanted to do Emi's route next but ultimately ended up playing Hanako's again because leaving her alone felt horrible u.u
Not that I regret it, out of all the routes I've completed so far it's definitely the one that touched me the most - still need to do Lilly's though.
It's only the beginning of the year but I can already tell that this is going to be one of the most memorable games of 2012 for me.
