Thanks mut! Inspiration comes from this being one of the first examples of a enemy "AI" in a commercial video game, and its logic is fascinatingly simple but cool when you disassemble the rom(explored by Montfort&Bogost in Racing the Beam, MIT Press). The one way to beat the enemy is to shoot the ball at the sharpest angle, but that's also what would tear up the screen the most, affacting only the player.
I love the idea of this "splitting" being represented auditorily, would try it out later!
