The Swapper

  (Edited: )

Thanks to Day[9]'s Day Off I've tried out this game, and after only an hour of play I must say I'm really liking it! Please discuss 

I want to mention this trick to swap between clones mid-air more reliably: while releasing the right mouse button to create your clone, simultaneously press the left mouse button to swap. This way you will almost never miss with the swapping ray after having created your clone.
