Hi Frog was the first big game from Die Kapitäne Media GmbH, reaching over 1.2 million downloads across iOS and Android. It took 3 years to develop with a 12-person team. I joined when the game had already been in development for about a year.
As this was our first mobile game, we had a lot to figure out. I played a key role in establishing professional development practices - implementing code review processes and quality standards, setting up an automated build server and CI/CD pipeline, and introducing analytics tracking for data-driven decisions. The technical architecture included real-time weather integration synchronized to the player’s GPS location, dynamic content that responded to weather conditions, achievement and progression systems, and cross-platform deployment.
We learned a lot during development. At the start, we didn’t even know what terms like “retention” and “cohort” meant, which led us to develop in the wrong direction a few times. But we figured it out, and the game resonated with players. The million+ downloads validated our approach and established the foundation for future projects at the company.
Built with Unity, C#, various backend services for weather APIs and GPS integration, and comprehensive analytics. The engineering best practices we established are still used by the company today.
