The game supports both online and local multiplayer. It also includes local drop-in co-op: a second player can join as Bandana Waddle Dee to play alongside Kirby.
Kirby can inhale enemies to copy their abilities (for example, Drill or Ranger). He can also inhale real-world objects to trigger Mouthful Mode, transforming into new, powerful forms; some copy abilities can evolve into stronger versions.
Rescuing Waddle Dees expands Waddle Dee Town and unlocks shops, leaderboards, access to townsfolk mini-games, and the ability to evolve certain copy abilities.
The game offers two difficulty settings: a lighter, breezier mode for easier play and a more challenging mode for players seeking greater difficulty.
Reviews report strong enjoyment and a universally positive summary (100% positive in the summary). Reviewers note the game is easy to play, features accessible local co-op, and is suitable for young children (around 5–8 years).
