Simple but convincing concept for a puzzle. Reminds me of the buttongrids where the four adjacent buttons always toggle with the button you click.
I liked the funny story, but all the text at the start was a bit lengthy to read. Maybe break it in multiple blocks: simple intro text, first level with only one button, text to announce two buttons, second level, text to announce next change, ...
But I liked it, it was a fun little intermission in my work day :-D
