Controller support added

Added support for controller.  Doesn't seem to work on brave though.  Tested in google and it's great!  I highly recommend using xbox controller on chrome.  

I also updated how  you clear enemies when circling.  It is now incremental so it tracks progress.  Before if you went the opposite direction it would basically start over.  
The other big update was a new boss phase i'm testing out.  The goal is to design multiple phases to RNG from and ramp up

Will do an overhaul of the page soon.  Focusing more on steam right now
