Definitely a spooky atmosphere. The vastness of the home adds to how surreal and strange the place is and adds difficulty when initially finding your bedroom and the tools needed to distract your parents.
The audio also does a good job of establishing an unsettling environment. I did notice that some of the walls didn't fully connect, but I think that you can easily fix this with some edits to the map.
The gameplay itself is a bit buggy (my mouse wasn't contained within the game window and I noticed that the camera moved very slowly compared to my mouse movements, so it was a bit difficult to control movement). However, the core elements are all there and the UI elements are clearly labeled, which helps.
I did manage to defeat the game and get some sleep!
This feels like it would work really well as a classic creepy horror game app (like Baldi's Basics or Hello, Neighbor) or something played on the browser. A little bit of overall polish on the UI elements, fixing small typos, etc. would really elevate the experience. Well done!
