I just got in too. Took a little bit to figure out, but it seems fairly easy to understand - the only problem is that I now have 8-9 wiki pages open every time I play.
*knows that feel*
But yeah, once you get into it, it's easy enough. It's nice to see how developed the Wiki's becoming; they're starting to add quotes and notes for the girls.
I'm really enjoying how leisurely this game can be played... I thought for sure I was going to have hell bouncing between this and other things. I tend to have a problem with leaving games on pause for long periods of time if I
see something shiny become preoccupied with something else... but this game actually rewards you for taking breaks.
