Once Upon a Katamari is an action casual game on PC that continues the Katamari Damacy series tradition of rolling a sticky ball through varied environments to gather objects and grow larger. Players control the Prince or other characters as they navigate stages set across different time periods, collecting everything from small items to massive structures in a satisfying loop of expansion and progression.
Gameplay
The core loop centers on guiding the katamari across cluttered surfaces filled with objects of increasing size. Starting small, the ball picks up minor debris before tackling bigger targets once it reaches critical mass. Controls allow for precise steering with options for standard dual-stick input or a simplified single-stick variant that keeps the focus on forward momentum and positioning. New support tools appear in stages as collectible freebies, including a magnet that pulls nearby objects closer, a stopwatch that freezes time briefly, a sonar device that highlights important targets, and rockets that provide a temporary speed boost. These items add strategic layers without altering the fundamental rolling action. Stages feature in-engine cutscenes that introduce goals or reveal key objects, and players earn ranks from D to S based on performance metrics like size achieved or speed of completion. King Tokens collected from stages unlock customization options for characters and emotes usable in shared spaces.
Game Modes
Single-player content revolves around a series of quests and stages that challenge players to meet specific size or collection targets within time limits. A dedicated select plaza called Super Stream grants access to ten additional quests that expand the available challenges. Multiplayer takes the form of KatamariBall, a four-player competition where participants gather objects while competing to deliver the largest haul to a moving spacecraft. This mode supports online play against other players or offline matches against CPU opponents, with scoring that rewards both collection volume and interactions like knocking items from rivals. The mode includes progression elements such as ranks earned through repeated play.
Sound and Presentation
The game features an expanded soundtrack that incorporates twelve additional BGM tracks playable during stages, blending energetic compositions suited to the rolling action. Visuals emphasize colorful, stylized environments across eras such as the Jurassic period and historic Japan, with the katamari itself growing in visual complexity as it accumulates mass. Character selection includes the Prince along with additional cousins that join the roster through updates, allowing variety in appearance during play sessions.
Current State and Updates
The title launched in late 2025 with ongoing support that includes new content additions like the Super Stream quests. These updates integrate directly into the existing structure, providing fresh stages without requiring separate launches. The PC version runs on standard hardware with verified Steam Deck compatibility for portable sessions.
Is It Worth Playing?
Player reception has been very positive, with aggregate scores reflecting strong approval for the refined rolling mechanics and the addition of strategic items that enhance stage navigation. The combination of single-player quest progression and the competitive KatamariBall mode appeals to those who enjoy casual action puzzle experiences with both solo and multiplayer options. Recent updates continue to add quests and audio tracks, indicating sustained developer attention. Those who appreciate the series' signature growth-through-collection loop will find the current version rewarding, particularly on PC where controls feel responsive and the new content extends playtime meaningfully. It suits players seeking lighthearted, accessible sessions rather than intense simulation or narrative depth.
