Ive read all the positive claims for this app from its creators who are very busy marketing it (free, but still . . . ) but I wish there were more to this--more EVIDENCE on the web that it works, more clarification in the instructions ( e.g. I still havent figured out the meaning of two different colored markers that flash after gathering grass bunches, particularly since I cant discern that Ive done anything to affect them), but mainly more interesting and varied things for the player to do -- the action seems endlessly repetitive. Is there ever going to be anything MORE happening? Will the grass chains never be more interesting? Perhaps thats the point? Ya gotta BE Zen to enjoy playing Zen?
