Like your take on choice-based stories. The texts are short&sweet - good job!
Was working on a similar idea in the past - kids exploring a story world with their parents. By making certain choices, a story continues to evolve. More text in that one, though ;-) Found a recording, if you are interested (in this part, the girl feeds some ducks and gets a feather in return): https://mitmachgeschichten.nicosteiner.com/media/videos/reading-book.m4v
