You are an invisible beast, hunting humans! Unfortunately, when you step within their hearing range, they will hear your odd heartbeat! In order to eat them, you must mask your heartbeat with theirs by tapping the shift or control key with each beat (or with the help of the visual indicator located at the top of the screen). They get more scared as they lose friends, making their heartbeat faster! You can also try to startle them by roaring with SHIFT, which has a five second cool down. Eat as many humans as you can before you get caught! Go for the high score! A stealth arcade rhythm game.
