The Swapper

The Swapper is a side scrolling puzzler that uses the gimmick of a "clone gun" where you can clone yourself up to 4 times and even force your consciousness change on to one of the clones in order to navigate through some base or something.

I don't really know the story, there wasn't one that I saw or a purpose to anything I was doing in as far as I played.   

There are advanced mechanics (probably) to the clone process to make to puzzle solving more difficult, like lights where you can't shine your clone gun, or lights where you can transfer your consciousness.  I'm guessing there is some acid bath you'll have to not fall in at some point to.  Wheeee.   Meant in a not-so-whee way.
