Makai Prince Dorabocchan is a platformer where the player controls the son of a powerful vampire. He accidentally opens a seal, unleashing monsters into the world, and must navigate six levels to save the day. Each level features a boss fight and requires the player to avoid losing their life energy. The game involves side-scrolling action with horizontal movement, and the player can use two methods to defeat enemies: by using vampire breath, which is similar to a gun, or by tossing tomatoes as bombs, which must be found beforehand.
The gameplay revolves around dodging obstacles while maintaining life energy, which can be replenished by collecting power-ups dropped by defeated enemies. These power-ups include energy, extra lives, and armor. As the player progresses through the levels, they will encounter a variety of enemies and challenges that require quick thinking and strategic use of the vampire's abilities.
