Insanity : Nocturnal Confusion 2 "The sequel" UPDATED!!!

[zenco2]

i'm liking it but i can't finish it. maybe i'm just missing something, but at the house that is flooded with water, i can't find the key. the note says look near the hart. (i think it was supposed to be heart) but i looked all around the pink heart thing on the bottom floor in the water and i can't find the key. i looked everywhere it seems like and i can't find it. someone help.
