Same. Tutorial having only contiguous cases made things quite unclear. I thought the starting point / endpoint where important to define the reflection axis and where it was, but no, only the axis gets defined

Yes - having a slightly more advanced tutorial puzzle, where you have to tap, swipe, tap, swipe, would be helpful.

Took me a few goes, but I did puzzle out today's. Very cool.
