The game was due to be published by Double Fine, but following that company's acquisition by Microsoft in June 2019, the Ooblets developers announced that they would instead self-publish the title. Ooblets was developed by a two-person indie game development studio composed of artist/ programmer Rebecca Cordingley and designer Ben Wasser, since 2016. As of July 2021, there are six locations in the game: Badgetown, Wildlands, Mamoonia, Nullwhere, Port Forward, and Pantsabear Hill. On June 12, 2021, the Port Forward update was released bringing a new region and new Ooblets. Ooblets has received frequent updates to fix bugs and introduce new features and locations. Unlike other life simulation games such as Stardew Valley, Ooblets replaces combat with a card-based dance-off system allowing new Ooblet seeds to be won and Ooblets to be levelled up. Ooblets, little creatures that the player befriends, can be grown from seed and used to perform tasks, like farming and machine operating, or dance-battle with other Ooblets. Players can also join one four clubs including Frunbuns, Peaksnubs, Mossprouts and Mimpuns. There are different quests that can be performed to unlock new shops and buildings, as well as improve the player's friendship level with the other residents. Players can purchase furniture and decor for their house, as well as seeds to grow on their farm. In Badgetown there are several shops including Meed's Seeds, Kibbonbon, Manatweee and Cuddlecups Cafe. The player arrives in Badgetown, a seaside town in Oob, where they are greeted by Mayor Tinstle and given a basic starting farm. The game combines the farming elements of Story of Seasons with the creature collecting and battling mechanics of Pokémon.
