Pretty simple case. I walked her thru the first 2-3 levels, and she just kinda quietly disappeared into it. I then had to explain the "times one" and "x/x" rules, which only took a few seconds. Next thing I notice is she has completed at least 15 levels (if not two whole "worlds"; app may have been deleted & restored at some point). At last interaction she was puzzled that you couldn't make the swirling vortex (to wit: 0) disappear leaving an empty tray ("that's just how it is, you can't have an empty tray" "ok"). I'll keep feeding it to her and keep you appraised.
