I adore this! Visual novels all have such a unique style, but this one really stands out among the crowd.
Having everything contained within one scene adds to the tension of it all (I mean, who wouldn't feel uncomfortable having to share an enclosed space with that eye-book?), and the way everything builds up bit-by-bit is ta real treat for the senses!
I've grabbed myself two of the endings so far, and I'm sure I'll be going for all of them! Keep up the awesome work, this was a real treat to play =)
