I think the very top animation on this page pretty much sums up this "game."
Her name is Mia, and doesn't she look bored out of her mind while getting fucked?
Now ask yourself this: "If the chick getting fucked is bored silly, how much fun will I have wandering the hallways hoping to stumble upon the next unlockable event?"
I made it to the morning of Day 4 before I abandoned this sad little story.
