Two new items in this update, Shield and Hover Ally. Shield prevents the player from being hit and wipes out the enemy variants upon collision, and the Hover Ally orbits the player while destroying enemy variants upon collision three times. The Hover Ally can be stacked, the Shield can not as I thought that would make things too easy for the player. I've also increased enemy speed and spawn rate as things felt a little too lax for my taste.

New sprite work and shield stacking has been put in the game for the latest update.
