EQUALIZR is a 2D shooter where everything in the game—enemy types, behaviors and formations, weapons, power-ups, levels and visuals—are all based on music chosen by the player. Whatever you pick, Equalizr will procedurally generate gameplay that matches the feeling of the music.
EQUALIZR is still in development, and will be released when it is exactly halfway between adequately and gratuitously awesome.
