Cloud Master is a classic Shoot'em Up game where you control a small character who floats on a cloud, shooting energy balls at enemies that fly towards you from both sides of the screen. You can collect power-ups to upgrade your abilities and visit shops to enhance your offensive and defensive powers.
The game features various stages, each with its own unique challenges, including a mini-boss halfway through and a massive final boss that's literally enormous. The game also includes some quirky elements, such as flying noodle bowls and bears wielding guns.
