Such a cool puzzle concept, I would definitely play a full release! I could easily see this being expanded to where you can record 2-3 separate versions of yourself, making for some really cool puzzles.
I wish there was more audible feedback for pressing a button, because sometimes I couldn't tell when a clone was actually on a button. I also think the clone might only use part of the recording? It didn't seem like the clone was fully mirroring my actions from the entire recording.
I had a lot of fun with this, and the art style is perfect. Great job!
