Hello everyone, I have created a Math plus path finding puzzle called Resonance. In this puzzle you start with easy 3 by 3 grids and go up to complex 15 by 15 grids. Complex grids may require you to spend an hour to solve it. Here is the link to it: https://play.google.com/store/apps/details?id=com.myComp.Resonance
Thanks for your time.
