I really enjoyed your game! Hopping between the different levels through the cassette tapes was a very interesting concept and I feel like it was pretty clear what I needed to do in each area. Also the use of 3D sound was very good for making me look at the events as the occurred. The environments for each area were also very well made given the limited time scope and how visually distinct each was. I'd say you might want to add some instruction to tell the player to sit on the couch after they put in the cassette tape, it took me a second to realize where to go. As well make the button to close the note the same as to pick it up, since that took me a bit to figure out as well
