I really enjoyed this. Very well-written and with a couple points (Harold's karaoke, Dan) that evoked a real sense of dread. The clickable text is a nice way to make the fiction interactive without relying on choices (and a nice way to present flashbacks unobtrusively). The endings all a bit less down-to-earth than the rest of story but I liked #4 anyway.
I kind of disagree with some of the other comments saying it's the good foundation of a VN or something -- it's really good interactive fiction and it's hard for me to see what visuals would add. The lack of illustration really lets the writing do the work in some key moments (climax of end #1)
