Beat Monster is a music-based, rhythm game. With a cute cartoonish art style and cute cartoon characters, you can tap the tiles to the beat of the music, and shoot the balls to destroy the monsters.

Each level will present you with a new set of tiles to be played, and the game will end when you've cleared all of the tiles. Along the way, you will also be attacked by various monsters, which you will need to defeat to continue to the next level.

You can also unlock various power-ups and items to help you beat the levels.

You will also be able to earn coins and spend them on new power-ups, as well as additional characters.
