I love the idea, and found the puzzles to be enjoyable to play through, but the house itself feels way too cramped. I got stuck quite a few times on objects and when the time limit is so strict, it can feel a bit frustrating. I also accidentally dropped items into the floor or other objects more than once and had to reset.
I think the biggest thing I found myself wanting was more clarity. There wasn't really clear signifiers of where the key went or what some objects were for (there's a lot of little squares and I'm still not entirely sure what they do). I also didn't realize initially that 4pm was the loss state - I saw the warning and kind of thought it would just boot me out at a certain point, but because it didn't, I just kept exploring.
Overall, I think this could be a genuinely entertaining puzzle game with a little more polish (and some bigger space to explore around!)
