I think the gameplay tended to make me move towards trying to brute force it until everything fit in, rather than a puzzle I could think about haha. This is probably because it's not clear what the colliders are for each of the objects, so you only really know if something is going to fit by just trying it until you get there if that makes sense. It makes it quite hard for me to visualise the puzzle and think of a solution, which is something I think I'd personally prefer.
For me I'd like to see it go down a path of perhaps objects are confined to a grid and can only be rotated 90 degrees so everything snaps. Then in order to spice it up and add some variety to the puzzles perhaps have different objects on different levels, maybe having oddly shaped objects or even some "rules" between certain objects, such as a lamp must always be touching a bed, or a fish tank isn't allowed to be too close to a computer etc for it to be a valid placement. Then it starts to get into a puzzle you can visualise and think about rather than just going ham at it until it all fits haha :P
Also an undo feature is always nice in these types of games so you don't have to restart the entire level if you mess something up.
The visuals were my favourite part and I also quite like the flow of the game with the menus and level restart transitions. Nice job!
