I played this on Armorgames.com already and I have to say this is one of the coolest escape games (even though technically it is not an escape game) I've played in a while. It has good mechanics and art, and the story itself has a frightening effect that makes you consider your final actions carefully. Good job.
The only thing that bugged me was the potion. I didn't know what ingredients to use and which not to use. Is there a piece of paper that tells you hidden somewhere in the house? I only found out by watching the tutorial.
