I liked this! Definitely buggy, I couldn't really guess properly my first time through because the front desk was in every scene covering the important bits :p But then I played it again and only the guide disappeared but I knew where to click to find them again.
The edutainment aspect was pretty neat. I liked that you did actually have to put all the clues together yourself and the game just let you be wrong up until then. I would have liked some music but eh! Had a vaguely creepy vibe in a good way.
