Art and audio are really cool, the graphics for the house are stunning.
I agree with other commentors that keeping shift pressed makes the game pretty easy, and there are few rooms with challenge so after a while it becomes a simple task of running in and visiting the places you already know will get you what you need. Maybe randomizing what is where would have meant there's a bit of a searching aspect to it, and replaying the levels would have been a bit more challenging.
I also was a bit confused about the story and what was going on. When the upstairs guy prompt you to steal a key, I don't think I found what this was for. I thought they were hadncuffed to the bed and might need help! but it didn't seem like anything was prompted after.
Would have been great if pressing shift also changed the player sprite at least a little, I thought it wasn't working at all at first.
