This is great. The interface is well done and interactions are smooth. The writing is cute and not intrusive. I used to play a physical version of this game called Zendo and loved it but haven't played for a long while.
This does seem like it would lend itself well to procedural generation. I barely had people to play Zendo with either, though some of my friends were occasionally willing I was the only one that actually liked it so it fell by the wayside.
