The one-shot build prompt
Build a browser game called "Sourdough Round: One Pool".

Concept: A fighting game set in a medieval bakery, where every action spends the same resource. Rendered in LEGO brick build.

THE CORE LOOP
Two characters, a short life bar, and a moveset of normals, specials and a super. Neutral, punish and mix-up are the whole game.

THE RULE THAT MAKES IT DIFFERENT
Every action spends the same resource. Movement, attacking, building and healing all draw from a single pool. Every decision is therefore a trade, and the pool must always be on screen.

REQUIREMENTS
- Input buffer, hitstop, and frame data as data files. Rollback or delay-based netcode only if online; offline must still expose training mode with frame step.
- Every mechanic reskinned as a baking process — proving times, oven heat, and ingredients that spoil on a clock.
- Studded bricks, clutch-power joints, minifig scale proportions, and explosions that separate into pieces not polygons.
- Runs in a browser with no build step. Vanilla JS or a single small library, ES modules, no bundler required to try it.
- Fixed-timestep update loop with interpolated rendering, so the game is frame-rate independent on a 144Hz monitor.
- All content — levels, entities, balance numbers — lives in JSON or plain data files, never inline in the logic. Tuning must not require reading code.
- Audio generated with the Web Audio API rather than asset files, so the whole thing stays self-contained.
- Feel pass, treated as a requirement and not as polish: hit-stop on significant impacts, screen shake scaled to magnitude, particles on every state change, and easing on every transition. Nothing may pop in or out instantly.
- Full keyboard support, a pause that actually pauses, and a settings panel exposing the tuning constants as live sliders. You will need those sliders.
- Respect prefers-reduced-motion: keep the fades, drop the shake and the parallax.

BUILD ORDER
1. The core loop with placeholder rectangles. No art, no audio, no menus. Make it fun as rectangles first — if it is not fun as rectangles, the look will not save it.
2. The twist, wired into that loop. This is where the design lives, so expect to rewrite step 1 once you feel it.
3. Content and balance, moved out into data files.
4. The look, applied last as a rendering layer over a game that already works.
5. The feel pass.

Scope: A month, honestly. If a system is taking longer than that, cut it rather than shipping it half-built.

Start by writing a one-page plan covering the core loop, the data shapes, and what you are deliberately leaving out. Wait for me to approve it before writing code.
How to actually use this
  1. Roll until something makes you laugh or makes you curious. That reaction is the only signal worth trusting at this stage.
  2. Copy the prompt for your agent. It ends by asking for a plan first — read the plan, and argue with it. That conversation is where the design actually happens.
  3. Build the loop with rectangles before anything else. If a grey box moving around is not fun, the pixel art will not rescue it.
  4. Then apply the look. It is deliberately the last step in the prompt, because a beautiful broken game is much harder to diagnose than an ugly working one.

The decks

Everything the randomiser can land on. Add your own insrc/lib/roll.js — each deck is a plain array, and every entry carries the line it contributes to the generated prompt.
