Energy Manipulation

This upgrade has multiple effects: Both the Deathballs and the Bluetonium are powerful weapons for clearing out traps, enemies and attacking Overlords.
 * 1) Your charged shots will now follow your mouse
 * 2) While in Blue Mode "Deathballs" can be controlled with the mouse by pressing the left mouse button on them and moving your mouse. The amplification of their attractive forces will tend to make them stick on walls though.
 * 3) While in Blue Mode the Bluetonium will follow your mouse instead of randomly moving about
