I bought it and have only played the first level so far, but I do have one interface suggestion. When selecting which node to play, instead of making the player tap the node, then go down to tap "Play" in the bottom right corner, how about allowing the player to double-tap the node to play it?
Now back to playing.
(edit) One more interface thing: After the first couple of levels, I don't really need the finger symbols to show me that I can move a piece, or double-tap to drop a piece. Or, if they were to stay on the screen, I would prefer them to be somewhere off of the sphere.
I'm enjoying it so far.
