just sit back and watch, this project was a mistake made when trying to update BulletHell, its actually pretty cool and mesmerizing though! the idea is that the bit in the center of the screen clones stuff and shoots it out at an angle and then it comes back down! the number in the top left of the screen is the turn angle which creates the illusion of speed until it gets to 180 then makes another sequence but double lines this time (not intentional)!
here are some cool timestamps: 110, 170, 190, 200
