I’m Mateusz, a game designer based in Wrocław, Poland. Over 6+ years in F2P games, I’ve moved from running live events to owning systems, product decisions and complete game development.
My background in psychology and UX design shapes how I approach motivation and usability. I combine that with hands-on implementation, analytical thinking and a willingness to test ideas early.
