Just grabbed the Windows version last night and have done a few routes in the christmas event.
The story for the prologue was very solid. I found it interesting and came to really like all the characters for their characters and not just the horny.
Since the Christmas event was written and produced after so much of Chapter 1 was through production, it was really, REALLY impressive to see the quality of expressions, posing, writing and character design improve so much.
defs worth following and playing!
