NOTES

An original single-player game, built alone in Unity. Game design, every system, the UI, the animation and the art style are my work and nobody else’s.

What it is

  • A single-player game about a ball, where guests carry influence and the hall is the board.
  • The Steam page is public — developer and publisher fujitoid, coming soon 2026.
  • Team of one. There is no second person on this.

How it is built

  • The simulation is fully DOTS/ECS. Jobs and Burst carry the data-oriented code, which is what lets a hall full of guests each run their own state.
  • Compute shaders and RenderTexture cover the passes that need them.
  • Custom shaders define the look. The art style is the point; the systems exist so the style can run.
  • State-machine AI drives what acts, guest by guest.

How it was made

  • A self-run agentic development workflow. I stayed the architecture owner and the quality gate rather than hand-writing every line.
  • That is the same claim as key-amnesia, made in a different medium: I build for agents and I build with them, and I can show both.

I am proudest of the art style.

Satan's Ball
The title card. The chandelier burns over the ritual hall.
Thirty-five seconds of play: guests are moved around the hall, influence spreads between them, and the round timer runs down.
The ritual hall, empty. The pentagram on the floor is the board the round is played on.
The influence view: the hall drawn as a blueprint with a pink field spreading across it. The hall in play, seen from above, guests scattered across the floor. The altar at the head of the hall, with the card hand along the bottom of the screen. A stage under the BLOOD sign, red influence lines running across the floor. A crowd of guests mid-round, one figure in green in the foreground. Guests gathered around the pentagram as a round resolves. The hall from a high angle, the long carpet running to the altar.
