Sorry to say, but rejection here appears a very sound decision. Imagine the appStore populated with a lot of similar apps… what a frustration for users.
Now, if you change your app to become really an educational app, showing examples of what could be a "complex" UI and a minimalist that perform the same task, that would provide some user value and may be pass the review.
Good luck.
