Lock a reel with the padlock to keep it and reroll the rest. Every roll has its own URL. Press R to roll. Weight is how hard the inspiration is on VibeDex — not a weekend promise.

How to actually use this

Roll until something makes you laugh or makes you curious. That reaction is the only signal worth trusting at this stage.
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.
Build the loop with rectangles before anything else. If a grey box moving around is not fun, the pixel art will not rescue it.
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 one-shot build prompt

Build a browser game called "Stall Round: Shared Blood".

Concept: A fighting game set in a farmer’s market Saturday, where you share one life pool with everything on your side. Rendered in soft watercolor.

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
You share one life pool with everything on your side. Allies, drones or party members draw from a single visible hit point or fail pool. AI partners must never suicide into damage the player could not prevent — their pathing and aggro are part of the fair ruleset.

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.
- Stall layout, perishable stock and a crowd that peaks then vanishes. Pricing and weather decide the day.
- Pigment blooms past edges, paper tooth texture, and wet-on-wet washes for skies and magic.
- 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.

Weight class: Heavy systems — cut hard. Cut systems rather than shipping them half-built — this is not a calendar promise.

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.

Twist · 35

you can only act on the beat
time rewinds every 30 seconds
one button is your whole control scheme
you play as the antagonist
death is permanent and inherited
there is no combat at all
the interface lies to you
the map is destroyed as you play
you control two characters at once
everything runs on a 60-second timer
you cannot see — you can only hear
every action spends the same resource
the world is rearranged each run
you escort something fragile
enemies get stronger every time you win
you can undo your moves but the world cannot
the camera has its own agenda
your score is also your health
all your inputs are mirrored
you are always falling
chat is a real control channel
you only get three verbs
the day/night cycle is the difficulty curve
everything is a subscription you can cancel
you draft the rules before you play
you only see what you have revealed
there is no HUD — the world is the UI
every choice locks the moment you confirm
failure deletes one of your verbs forever this run
you share one life pool with everything on your side
nothing is explained in words — only signs in the world
a cursed token must be held, passed or dumped on a timer
you win by making a deal, not by destroying the threat
critical information is shown once, then gone
the playable space shrinks on a clock you can read
