A fun game and great costumes, though it could be expanded on.  Maybe it was a time issue, but as soon as (spoiler) was revealed to be the murderer, the story ends. The detective does not explain his deductive reasoning to the group and we never even learn (spoiler's) motive for killing the lady.

I also would definitely recommend making the text on your game page a brighter color to stand out from the black. Medium grey on black just doesn't stand out very well.
