Definitely one of my favorite classics next to The Dead Case. :)
All the many clues, characters, and dialogue choices were a nice touch. ^_^
Also, maybe it's just me, but I actually liked the little girl. :? Maybe seeing her for real in that atmosphere would be creepy, but I always wanted to believe that she was related to the victim who died and was his daughter, so she wanted to help the police get justice on him (in a more or less innocently childish way though).
Then she got way different in the sequel. :p
Also, Kill Them All is probably one of my favorite songs in a flash game next to the songs in Memohuntress such as "Rose Inn" and stuff from The Sagittarian series, and maybe TCT (The Color Tuesday's) "Rose at Midnight" (Oh yeah, Epic Battle Fantasy is also good. :))
My only complaint is that the bad guy always seems to be the same. :( I think someone else said that too somewhere (might not be here) a very long time ago.
