GeoFlag is made possible by the work of many open-source contributors and creators. This page acknowledges the third-party libraries, assets, and tools used in the game.
Country flag SVG collection by Panayiotis Lipiridis. Used for the 154 country flag images displayed throughout the game.
Animation library used for menu choreography and game-feel polish.
Framework for building cross-platform desktop applications.
Primary user interface typeface, designed by Colophon Foundry, Jonny Pinhorn, and Indian Type Foundry.
Display typeface, designed by Phaedra Charles and Flavia Zimbardi at Undercase Type.
All character art, icons, hexagonal previews, landmark vignettes, transport vignettes, and background images were generated using Recraft AI image generation tools under a paid commercial subscription, granting full ownership and commercial use rights.
All sound effects in GeoFlag are generated procedurally at runtime using the Web Audio API synthesizer. No third-party sampled audio is used.
Country and territorial boundary data is derived from Natural Earth, a public domain map dataset created and maintained by Tom Patterson, Nathaniel Vaughn Kelso, and contributors at the North American Cartographic Information Society (NACIS).
Country and US state boundaries follow internationally recognized standards as defined by the United Nations. Disputed territories are depicted with dashed borders consistent with standard cartographic practice for contested regions.
GeoFlag was developed by Andrey Ogorodnikov (Ogo Studio) using Claude Code, an AI coding assistant by Anthropic. Per Steam's guidelines, AI-powered developer efficiency tools do not require disclosure, but we believe in transparency about our development process.
To my daughters, who inspired this game. To the open-source community, whose generosity makes small studios like ours possible.
