Plantera 2: Golden Acorn is a game where players create a garden around a magical oak tree with the help of round blue creatures called Mellows. Players can harvest golden acorns and expand their garden to include various plants, animals, and creatures.
Players begin the game with a small garden, gradually leveling it up through the purchase of new crops and gaining experience and money. Additionally, players can decorate the garden with items to attract new flora and animals to the garden.
The game offers players the option to harvest plants and trees themselves or let the Mellows do it for them. Players can decorate their gardens and unlock new items as they progress. The goal is to expand and improve the garden to make the magical oak tree grow bigger and possibly discover its secrets.
