Mission Revision

(An entry to the Black and White Jam #8↷∞)

Mission Revision is a shoot-em-up where your past can affect your present!
Instead of dying and dying again with no help whatsoever,  You can now progress through the level with the help of your previous attempt! (Sadly, they'll expire when you did)

However, depending on your collaboration with your past you can coordinate better than you do with a friend! (Or learn your past is more annoying than your present!)
