Once Upon A Katamari

Once Upon a Katamari is an action game that continues the Katamari Damacy series running for over 20 years with new stages, mechanics, and a time-travel theme. Players control the Prince or one of 68 customizable cousins as they roll a sticky ball, or katamari, across environments to collect objects and increase its size. Levels span multiple historical periods such as the Jurassic Era, the Ice Age, and Edo Japan, each featuring themed items and objectives. Stages may require collecting specific object types or reaching a target size within a time limit.

New features include power-ups such as the Rocket for short speed bursts and the Radar for locating specific items. Each stage contains hidden collectibles like crowns and gifts, unlocking customization options and bonus challenges. Progression is tied to collecting these items to access new eras and levels.

Multiplayer mode KatamariBall supports up to four players, either online or offline, competing to collect and deposit the most objects. The game features a 36-track soundtrack inspired by Shibuya-kei pop, with music selectable from across the series’ history.
