I totally agree, having fruit thrown in to part of the "dot-trail" would be very nice on the border. I just noticed that the blue double line outlining the joysticks does not go all the way around, is there any particular reason for this and have you tried to make it a complete square.
Still hard to visualize without seeing those changes. Who knows, the complete square may look cheesy, just wondering if you had done a prototype with a complete square.
God, that was a rambling post.
