I do love when people tackle narrative in game jams, because it can be hard to inject a story into such a small segment of a game, so when you find yourself intrigued, it means it was done well. And I think you did so well! from the music and the scene of waking up in the middle of night, to walking through a dimly lit apartment, my curiosity was piqued to see it through!
Also kudos on the art and atmosphere. well implemented. I did however struggle to find the sticky notes and was lost on "what to do" at some points. if you were to continue working on it, I'd say think about the player experience and extra ways to draw attention to the things that need to be found, such as audio cues or other eye catching events.
For the sake of the time-limited jam, it was a really enjoyable tale!
