This game was incredibly fun! The puzzles were a good challenge for the first few levels of a game like this, and the progression of difficulty was I think incredibly natural, the introduction of the falling platforms mechanic was executed pretty nicely as well in my view.
The only real downside to the game was that I often (at least once per level) had an attempt end due to some of the inputs not actually being executed. Whenever this happened, the little pip at the top of the screen would stay grey (and if ones after it continued to get executed, they'd turn red, so it's just one or two that'd stay grey in the middle). It's an annoying little bug that I hope is ironed out in one of the future iterations, but I get why it wasn't fixed or maybe even noticed in this first 3 hours.
Great work!
