Very clever, fun and addictive

I have been playing this game with my 7 year old and it is so incredibly well done. The difficulty of the levels slowly increases and my child I and I could literally spend hours together trying to create the most elegant equation for maximum points (yes the cute characters and simple rules are just a gateway to the kinds of equations any of us will remember from middle school). Knowing the complication that goes into good graphic design, coding and the art of teaching math in a way that is both fun and usefully instructive I am blown away.
