Sounds good. I don't mind a slow build up so that's not a problem, all I care about is story that's enjoyable (or at least interesting) to read through - looks like I'll be happy with it.
Length is my only worry to be honest. Not because I don't like long VNs (or games in general) but I have a bit of a problem sticking with things at the moment. It's what prevents me from starting SG and finishing some other games I've been playing on and off for... years in some cases. Mind goblins can be infuriating in the worst ways sometimes.
