Four games, a living room, and not one art file.
Every one of them runs in a browser tab. No install, no launcher, no asset download — every texture, mesh, sound and note is written in code the moment the page loads. Open one on a phone and it plays.

Kart Royale
Golden hour, eight karts, and a drift ladder that pays you for holding the angle longer than is sensible.
Anti-gravity racer · Live
Umbra Nine
Cook in the light. Radiate in the dark. A lap that crosses the terminator twice at 770 km/h.

Homie
A Mac Mini behind the television that runs anything, knows who is in the room, and can make you a game. Everyone’s phone is already a controller — no app, no account, nothing left behind.
A builder never
grades its own work.
All five projects were built the same way: write down what good looks like before you start, split the work into pieces that can improve without each other, and give every piece a critic that did not build it. The critic compares the piece against the written bar and sends it back until it clears.
The rule that makes it work is the separation. A model reviewing its own output finds it excellent. A model handed a rubric and a frame it has never seen finds the seams.
Write the standard down first
Each project starts with an art-direction document carrying numbered calibration bands, so "good" is a score with a defensible floor rather than a mood. 0–40 reads as programmer art. 85+ is the only passing grade.
Cut along seams that don't move
Track geometry, materials, flight model, audio, HUD. Each owns its own files and its own numbers, so two agents can work at once without a merge that silently loses a fix.
A separate pair of eyes per piece
A fresh agent gets the rubric and a captured frame, not the diff and not the intent. It scores against the bands and writes down what is short. Halocline alone accumulated 230 of these reviews.
Instrument what eyes can't judge
Whether a drifting lap is genuinely faster than a clean one. Whether the key-to-fill ratio on the road is really two stops. Whether the game survives losing its WebGL context. Those are harnesses, not opinions.
Stop when the critic runs out
Not when the builder is tired. The loop ends when a critic that has never been happy cannot find the next thing.
