Sonar Beat

Sonar Beat is a musical rhythm arcade game with a twist: the notes follow a spiral structure, so the ones you miss will remain and will move forward towards your center. If they reach it, you’re dead. You play through a radar interface using your sensor cone to detect enemies approaching the center. Compete in online leaderboards for the highest rank and challenge your friends to see who gets the highest score
