In a nutshell, it's a high-speed game where you defeat enemies by jumping.

The goal is to defeat as many enemies as possible while your soul inhabits another person's body for a limited time, during which the body gradually decays even if you do nothing.

It's a game focused solely on defeating enemies: randomly assigned targets appear, and once you wipe them out, you move to the next target.

Along the way, you'll find shops where you can buy items to strengthen your character, weapon shops, and hospitals to heal your body. You'll need to plan how to spend the money you earn from defeating enemies.

Bosses also appear during your journey, and defeating them unlocks the next stage.

Playing the game unlocks more types of bodies you can use, allowing for repeated playthroughs.
