Cloud Master is a platformer where you control a small character who floats on a cloud, shooting energy balls to fight enemies that fly at you from both sides. You can collect power-ups and visit shops to boost your abilities, both offensive and defensive. The game has various stages with mid-bosses halfway through and the final big boss.
The gameplay involves navigating levels while avoiding obstacles, jumping over pits, and using your energy balls to defeat enemies. Collecting power-ups will give you extra shots or increased health, helping you progress through the challenging stages.
