this is a very good game and fun to play however it really doesn't seem to take into consideration how much the user's view is obscured when using your finger. it is much better suited for phones that us a stylus as oppose to your fingers. other than that it's a great concept.
the lag is worsens as you add fruit to you tree, but overall it is cute and can hold your attention on a five minute bus ride after that it becomes monotonous.
