Cute art, really fun idea, and I think these sort of "figure out what to click" games have a lot of potential. The theme makes me imagine I have some sort of limited reality-manipulation powers and need to figure out what will work which is a cool fantasy.
My only gripe are the controls - if I don't guess where I'm supposed to put the object (and it really is guessing) or misclick, I then have to wait a second or two until I can click again, and the audio cues make it feel kinda unresponsive, or at least confusing. I would've skipped the mechanic of object slowly falling back to place and just make it immediately clickable again. I think that would be an easier change than adding more objects or hovering, and that way clicking around and looking for interactive elements would be more fun.
