Enjoyable game with a fantastic concept! I only wish that some of the stuff that could change were smaller details, like the color of the fish or the face on the TV (I'm guessing that would be hard to implement for the jam).
I think you could definitely take this basic build and expand it to a full game. For example, the lights suddenly going out is a classic murder mystery trope - maybe you could turn it into a murder mystery where you figure out the murderer based on how the objects in the room change. Game is still fun as a straightforward memory game and I think it has a lot of potential!
