Really nice job, I really like the art style, game play and music. The game play is a very original take on the theme and the art style kinda resembles return of the obra dinn which is really cool. Very small critique is that there is nothing on the floor at the start so its a bit hard to tell if you are moving unless you are looking at the sky, also I got stuck when building my tower because nothing was in reach so I had to reset. It could be useful to have the objects so slowly drifting through the sky to prevent this situation.
