I do everything when it comes to Game Development! Here are some of my highlights
01 — 2022 · Solo dev — Unity, C# · built in one week
Ghost Cube
An early project took only one week of development
This was one of the first games where I actually had an understanding of what was going on with Unity and coding. It took me a week to create, and is one I think I can still show off. Created in 2022.

Dumb Game for Stupid Idiots
Yet another Foddian game.
A first-person Foddian climbing game where you climb a tower, no checkpoints, one bad fall and the run is over. Built over a few months in 2025 to go deep on gameplay systems rather than scope. - Custom event system — rewire lighting, cutscenes and triggers from the inspector. - Full save/load — player position, world state and lighting, versioned across builds. - ScriptableObject dialogue — custom editor, with NPCs that react to player progress. - Spline progress tracking — live completion percentage along the climb path. - Interaction framework — hold-to-collect with progress bars, shake and animation hooks. - Feel & polish — layered ambience, surface-aware footsteps, subtitles, options menu.
- Unity 6 (URP)

- Solo (all code, design & audio — external 3D models)
