This release has the following changes:

• Fix to the problem where enemies would sometimes move a couple pixels relative to the background.  This was occuring when the seam in the background would reach the point where I needed to wrap.  I was always moving to x=0 instead of taking into account that the scroll speed may have moved it beyond a full image length past x=0. That pixel delta was causing the jump
• I made the electrode towers a little smaller to make them not such an easy target
• I randomized and shortened the electrode tower's off time a little to make them more of a factor in the gameplay
