I won the "serious games funding" from the state of NRW in Germany at the end of 2023 for my game Blueberry. This gave me the chance to put together an international team of freelancers for programming, art, animation and audio. I developed the complete UI and UX as well as level and narrative design for the game, implementing the UI in Unity in close collaboration with my programmer. Blueberry will be released on Steam, Xbox, PS5 and Switch on 28th May 2026.
