very neat. the rotation really worked intuitively, so whatever solution you came up with for rotating stuff in 3D should be the golden standard from now on. would have gladly played 10 more levels with a bit more complexity.
super-random-sidenote: have you by any chance ever played the 1991 classic puzzler SUPAPLEX? because your visuals (especially from the itch.io background) AND the name totally reminded me of it and how I loved it. and now I just found out, that it's actually in the app store, so thank you I guess. gosh, I'm rambling. sorry.
