The story was really compelling - someone forgetting everything mid-crime. I kept thinking if he brought her to this weird house with no windows to murder her but that just may be too dark. :P
The environment looked nice and spooky. Unfortunately, I couldn't figure out how to get inside the room in the attic (if that is what I was supposed to do) and got stuck there.
EDIT: Okay, I tried it again and then I couldn't find the laundry room. The key I got in the dining room worked on the brown doors but there was nothing in the rooms inside. I probably missed something , this type of game is just not for me I guess. Maybe you can make a walkthrough video for those of us who couldn't finish the game just so we can get the story :). As for feedback, I would suggest you make the stair movement smoother and add some more sound effects.
