I make short, tense games, and tools when the games need them.

Unity developer, C#. My games are built around one strong mechanic: an echo replaying your moves eight seconds later, a wolf that learns from your traps, a world that only exists one colour at a time. Five of them play right here in this page. On the side, six editor tools published on the Asset Store, downloaded more than thirteen thousand times.

Chapter 02 — ECOp. 02

ECO

Session 1 — your echo (blue) replays the path you just traced, eight seconds behind.

Your past catches up with you, eight seconds late.

ECO is a puzzle-platformer where every move is recorded and replayed by an echo eight seconds later. A button to hold, a door that needs two: your self from eight seconds ago does the job while you move on. My most ambitious project, playable solo or in co-op, with a level editor whose creations are shared online from inside the game.

DIG or DIE

1st place — game jam
Level 6 — lay your traps on the blocks before the wolf arrives; the inventory below counts what is left.
Fig. 1 — Level 6 — lay your traps on the blocks before the wolf arrives; the inventory below counts what is left.

The wolf learns. The shepherd traps.

An eleven-level puzzle where you place traps before the wolf arrives. It dies, it learns, it comes back avoiding what it saw. Kill it when it thinks it knows everything. Short, tense, pixel art, playable in the page. Made in 48 hours, first place at its jam.

Chapter 04 — Color GAPp. 04

Color GAP

Jury’s Favorite — Global Game Jam 2026
The world before the fracture: white, low-poly, silent.
Fig. 1 — The world before the fracture: white, low-poly, silent.

A world that only exists one colour at a time.

A minimalist platformer driven by colour, rhythm and perception. A pristine world fractures into three primary colours; every jump cycles the visible one, and the other two's platforms vanish. Jumping means choosing what exists when you land. Jury's Favorite at the Global Game Jam 2026.
