now you always have all upgrades, the bullets fire super fast, all attacks are rainbow, the big laser is super big, all attacks one shot enemies, you have a giant spinning laser, enemies give a ton of points, and you have a LOT of health. (it doesn't really matter how much health you have since you have the shield) Edit: I made the red lasers come more frequently to make it a little harder, but I don't think it really matters since you have a shield and a lot of HP.
STROBE LIGHT WARNING!!!!!!!!!!!!!!(because of the rainbow attacks)
