A cool tetrisy game! I love the art. and the gameplay is interesting, once I got the hang of it. On first impression, I was very confused why my building parts weren't fitting in. It took me a couple minutes to figure out that the decorative elements like ladders, trees, chairs, etc, were actually relevant to the gameplay.
I think if you highlight the cells that will be blocked by these decorations in red while you are dragging the building around, then the game would be much more accessible and very fast to pick up. It felt slightly misleading to not highlight those cells on dragging
