CPT gun

Browse Source 
new level boss that fires 2 streams of small bullets that chase you

mod: add a CPT gun to your inventory that rewinds your history, reverts your health, position, velocity for 10 seconds
  I expect that spamming rewind has some overpowered combos.
  Let me know what you find, and your ideas on balance.
