You mean like literally the alternating page stucture itself? huh that is a weird request. The Raymond Smullyan logic/combinatorics puzzle books all follow a similar format conversationally with little problems that inch upwards, but the answers and explanations are deferred to the end of each chapter. But is has a similar tone. To Mock a Mockingbird is the one I would recommend, it is about SKI combinator calculus stuff but with a interesting bird analogy.
The Little series is honestly doing a very unique thing pedagogically, I would be surprised to see many reocmmendations of similar things.
