This feels like a finished game! You did a great job keeping to a simple core mechanic and expanding on it. The puzzles are well paced, and the game feel is there.
Although I feel like the "timed platforms" (the ones that vanish without any input) are a bit of a counter pattern for the type of game. Because if I understood correctly it requires the played to time its first recording with it, which in my opinion causes dead time.
Still this game is fantastic and I'd love to see more of it! Good job!
