It will drain the life out of you :)
Word of advice: Pack a Big Bag of Patience.
I mean it! Well designed game, great story, fun…hilarious, but if you haven't done this before…good luck! It goes like this:
"It is a beautiful story about a beautiful young girl that was held against her will by a mean vampire"…mm neah' I'm sounding like a girl...actually I'm playing a girl so I guess it's ok! Anyway you'll have fun playing this game believe me, some brainstorming required indeed and lots of walking around but eventually you'll find yourself at the end in no time probably craving for some more!
There is one thing though that you should do! You might want to call your best pal over so he will be there to help when you'll start losing your mind! :) Don't get me wrong but ...well you'll know what I mean!
