I've been playing this for a few years now and just love all the references to other games that you put in! It's QUITE clear that you've played Earthbound, and there's clearly a few other games that you've played or at least are familiar with!
How close are you for being finished with HC? There's a lot of girls that still need love quests, but given that's what you've been focusing on lately thinking the "main game" is more or less finished and you are now just working on getting the side stuff done. I did discover the hard way that taking to Chimei when she's max heart will start the quest (not checking the wiki first) woo boy was that a mistake! Suggested level 40, and I was around half that. (got slaughtered pretty badly). Oh well...check wiki to make sure of when I should start love quests now!
