Neato! Always considered doing this in Twine 2 before, and as you show here it definitely works..! My only suggestion is to add some basic stats to track e.g. how many spills the player cleaned, what children they've found/helped, how much Energy they used (and how much they have left at the end), and maybe a few achievements for e.g. when Kenneth and Orville are reunited. Just so that each run can easily be shared with others.
