The developer behind Marrow Tap.
I’m Mariusz Klimek — a freelance game developer with 7+ years of professional experience, working with studios, startups and indie creators on visual novels, adventure games, 2D games and pixel art.
I work both sides of the craft: client projects delivered to spec and my own games shipped commercially on Steam. Fiverr has vetted me as a Pro in both Game Art and Game Development, where 55 reviews average 4.9★.
I deliver complete games, not just code: a solo technical lead with a trusted production network — artists, musicians, and voice actors — assembled per project. One point of contact, full-team output, without agency overhead.
— one sentence on where the name comes from, so it doesn’t read as random.
Tools & engines
Outside games I have a general TypeScript/web background — it shows up in tooling and build pipelines, not in what I sell.
