Controls : Arrow keys to move, space to shoot. Press the V key to change your color (Black or White). You absorb bullets of your color and are harmed by bullets of the other color. There are two modes. Classic mode - fight a boss at the end. Endless mode - fight until you are killed.
I made some edits to Super Polarity, people pointed out some things that I could have done better/ought to change. Enjoy! Changes: Enemies shoot faster and have more health. The boss is smarter and shoots both types of bullets whilst defending itself. The player has less health and your bullets are slower. Submit your scores from Endless mode in the comments!
