Ghostbutter
Independent game development in Japan
About Me
My name is Konstantin Kopka. Born in Germany, I'm a Japan-based game developer specializing in porting, performance optimization and engine tech.
I spent over a decade creating games as programmer, artist, designer and composer. Fluent in German, English, and Japanese.
I see games as worlds where players can step into the unknown and face their fears.
