ABOUT

Marcin Smoła (fcolor04) — indie game developer and programmer. Creator of Mr. Cloak, Jump Challenge!, GeoJelly and Land of Mushrooms, plus open-source software projects. Available for work.

Hi, I’m Marcin Smoła — most people online know me as fcolor04.

I’m an indie game developer and programmer. I build and ship games under my publishing name Nova Reactor (titles like Mr. Cloak, Jump Challenge!, GeoJelly and Land of Mushrooms), and I work as a programmer at Source Byte, where I’ve contributed to shipped console and PC releases since 2021.

What I do

  • Gameplay & systems programming — primarily Unity (C#) and Godot (GDScript).
  • Lower-level tinkering — C++, Zig and Odin, including graphics bindings and tools.
  • Tooling — editor extensions and pipelines that make day-to-day dev faster.
  • Shipping — I care about taking features from idea to a release players actually hold.

Find me

I’m open to work

If you’re looking for a developer who can own a feature end-to-end — gameplay, systems, tooling, or performance — I’d love to hear from you: fcolor04@pm.me.
