Good vertical slice, proving the concept. Before adding any more features, I would replace the falling props with proper models made for this. Currently a lot of the models, like the fireplace, are not made for this. Gameplay can already be improved by being particular with what kinds of shapes drop, plenty to experiment with and many directions to take it. A proper art direction and identity would also uplift this alot. After that's adressed there are so many ways to expand and add to this fun little concept.
