Sponge Hammer Games

Sponge Hammer Games is a British independent game developer and publisher founded in 2018. Based in Warwickshire, it creates original intellectual property for mobile devices and PC, with work spanning educational experiences for preschool children and stylized action-adventure games. Its artists, designers and programmers collaborate across the United Kingdom and continental Europe.

The studio’s approach emphasizes storytelling, player well-being and thoughtful game design. Its early work focuses on calm, accessible entertainment for young learners, while its expanding portfolio also explores steampunk settings, combat and procedural challenges for PC players. The company develops and self-publishes its own games, bringing together narrative design, character art, animation and cross-platform development.

From interactive stories to PC adventures

Development of Flatstone Grove began in May 2020, prompted by the team’s observation that young children lacked calm digital entertainment designed around their needs. Released for iOS and Android on June 21, 2023, the interactive storybook and activity app is intended for children aged three to six.

Through the adventures of Marci the bee, it introduces themes of kindness, empathy and care for nature. Its design excludes external advertising, in-app purchases and high-stress gameplay loops, making those choices part of the experience rather than relying on conventional mobile monetization mechanics.

The Drifting Crown extends the studio’s work into PC gaming. In development and showcased at DreamHack 2026, the Victorian steampunk action-adventure roguelike combines combat runs, modular world-building and skill-tree progression. Its premise asks players to rebuild the world and rescue the realm’s last standing pub, giving the project a distinctly British comic thread.

Across these projects, Sponge Hammer Games combines its interest in narrative-led experiences with different audiences and formats: gentle exploration and learning on mobile, alongside action and progression systems on PC. The studio’s supported development capabilities include Unity, 2D and 3D character production, and deployment across iOS, Android and Steam.
