In fact, my only criticism is the lack of music. I kept imagining how much cooler it would be if there was some kind of creepy soundtrack not unlike the kind often associated with Puppet Combo games. I also noticed that despite saying so, the game doesn't actually "pause". The killer can still find and murder you.
At any rate, bravo for a job well done. I look forward to whatever else you come up with! (I don't know why people are forgetting to rate this game. It gets a definite 5-star from me.)
