Hey, I'd love to hear more about it, and I'm sure the founders of DragonBox makers We Want To Know would too, since they had kids twice this age in mind when they designed the game... reach me on sversille@flirtatiouslabs.com and I'll be more than happy to pass on your feedback directly to the founders.
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.
