Ok so I have some feedback from the initial release and here is what I am going to add for the next version.

1) Difficulty...Use touch or shake to change difficulty level and display it on the map.

2) Slight graphics change.  Chrome ball and new splash screen.

3) Bug fix.  Some have reported a bug where the ball can get caught in the wall.  This is fixed and will be in the new update.

4) Some additional features.  I am thinking of starting with ramps and antigravity

Look for it sometime next week.
