Pond Keeper Demo Released for Earth Appreciation Festival 2025 on Steam

Fans of cozy simulation games can now try the Pond Keeper demo on Steam as part of the Earth Appreciation Festival 2025. The festival, which runs from April 1 to April 8, 2025, highlights games that celebrate nature and environmental stewardship, and Pond Keeper fits squarely within this theme.

Pond Keeper is a cozy game where players take over a neglected aquatic world and transform it into a thriving paradise. Players breed, sell, and collect colorful fish, unlock new biomes, decorate their ponds, and watch their natural sanctuary flourish. The game emphasizes restoration and care for aquatic ecosystems, aligning with the festival’s focus on nature-themed experiences.

The Earth Appreciation Festival, now in its fourth year, features over 160 games across two recurring themes: “Nature” games that showcase wildlife, sustainable agriculture, evolution, and thriving ecosystems, and titles that inspire players to cherish and protect the planet. In 2025, the event reached over 3.3 million unique visitors and included a digital showcase where 29 games shared news and announcements.

The festival is organized in recognition of World Earth Day and encourages participating developers to develop charitable donations to environmental causes. In 2026, the festival will return with expanded collaboration, including partnerships with Cool Earth to support rainforest restoration efforts.

Players interested in trying Pond Keeper can access the demo via its Steam store page during the festival window. The full game invites users to build and maintain a personalized aquatic ecosystem, offering a relaxing yet engaging experience centered on renewal and biodiversity.

As part of the festival’s mission, Pond Keeper offers a playful yet meaningful way to engage with themes of ecological restoration — one virtual pond at a time.
