Objection Arena

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Recreate a responsive browser game titled “Objection Arena,” a turn-based verbal courtroom duel against a simulated AI prosecutor. Use a dark, warm, theatrical courtroom visual style: a Three.js 3D scene fills the background with a dark brown courtroom, back/side walls, judge bench, defense and AI podiums/desks, witness table, chairs, a red carpet, gold trim, and a small gold justice scale. Include a glowing blue faceted AI prosecutor orb floating above the AI podium and a rotating green defense counsel halo above the defense podium. The camera is a mostly fixed, slightly elevated perspective looking into the room, with subtle camera sway; the orb slowly rotates and bobs, the defense halo rotates, and the scales gently tilt. Use warm amber key lighting, a cool blue rim light, shadows, fog, and a dark brown/red/gold palette. The UI is a translucent, rounded, gold-bordered overlay over the 3D scene, with cream text, amber headings, and green/red/blue status colors. It must work on pointer/touch and resize responsively, switching from three-column layouts to stacked mobile layouts.

The top bar always shows the large serif title “Objection Arena,” the subtitle “Verbally duel a simulated AI prosecutor. Win the jury before your credibility collapses.”, and an AI Difficulty range slider from 1 to 11. Display the current value and named tier: 1–2 Sleepy, 3–4 Polite, 5–6 Sharp, 7–8 Ruthless, 9–10 Exhibit Storm, 11 Proof Demon. Begin at difficulty 6 (Sharp), but let the player change it before or during play.

Start in a docket screen titled “Choose your impossible case.” Explain that three fresh courtroom disasters are on the docket and the player should defend a client using legal-sounding chaos, cross-exams, exhibits, and jury appeals. Include a “Generate three new cases” button. Show exactly three clickable AI-generated docket cards. Generate each procedurally from absurd subjects, defendants, motives, and twists. Each card shows a title in the form “The People v. [defendant]”, an accusation involving a bizarre stolen object, a claimed motive, and a strange evidence/witness twist. Also show Stakes 25–100, Absurdity 20–100, and a defense angle: “weaponize confusion” when absurdity is over 60, otherwise “calm reasonable doubt.” Example content can include a nervous raccoon accused of stealing a space casino’s lucky dice, a talking vending machine and a haunted aquarium’s prize squid, or a suspiciously polite goblin and a wizard academy’s enchanted stapler, but keep generation procedural. Clicking a card starts the case.

The battle screen is a two-column courtroom interface. The left/main court panel shows the selected case title and description, a “Round 1 / 7” badge, and three horizontal meters: “Your credibility” starting at 100 with a green fill, “AI credibility” starting at 100 with a red/orange fill, and “Jury leaning” starting at 50% defense with a blue/purple fill. Beneath them is a scrolling transcript of courtroom bubbles. Opening entries are a centered Judge message saying court is in session and identifying the client and stolen subject, followed by a red AI Prosecutor opening statement. Player lines appear as green right-aligned “Defense” bubbles; AI statements are red left-aligned “AI Prosecutor” bubbles; judge messages are centered gold-tinted bubbles.

Each player turn presents four randomly selected action cards from an eight-item deck, plus an optional custom argument textarea limited to 180 characters and a “Present Custom Argument” button. The actions and their fixed intent are: “Object on vibes” (attack AI confidence), “Cross-examine witness” (ask an impossible question), “Produce counter-exhibit” (reveal a chaotic helpful exhibit), “Appeal to jury” (less AI damage but strong jury gain), “Legal technicality” (exploit an unread clause), “Blame the timeline” (risky but effective in absurd cases), “Humanize client” (protect defense credibility), and “Demand proof chain” (force the AI to explain every exhibit). Clicking an action immediately adds its prewritten dramatic legal-comedy line to the transcript, disables the action controls while the AI responds, updates meters, then after a short delay produces an AI rebuttal and advances the round.

Implement the actual turn math and win/loss rules. Each action has power, jury shift, and risk values: Object on vibes 13/4/5; Cross-examine witness 16/1/8; Produce counter-exhibit 18/-1/11; Appeal to jury 9/11/3; Legal technicality 15/2/7; Blame the timeline 20/-4/14; Humanize client 8/13/2; Demand proof chain 17/3/9. On the player turn, roll a random 0–8 and subtract action power plus an extra 5 when the case absurdity is over 60 and the action is Object on vibes or Blame the timeline from AI credibility. Subtract risk plus floor(difficulty/2) minus a random 0–6 from defense credibility, clamped to 0–100. Shift jury by the action’s jury value plus a random -3–3, minus floor(difficulty/5), plus floor(defense roll/9), clamped to 0–100. For custom lines, score based on length and words: start power at 8 plus up to 12 for length, jury at 2 plus up to 10 for length, risk 6; add power for legal words such as objection, evidence, proof, witness, jury, reasonable, doubt, custody, motive, and intent; add jury for dramatic words such as your honor, absurd, impossible, truth, cupcake, royal, timeline, and crumb; exclamation marks add power and risk; lines under 18 characters are weak. Clamp custom power to 4–28 and jury to -4–18.

After each defense action, the AI attacks. Base AI defense damage is 6 plus difficulty*2 plus a random value from 0 through difficulty+2. AI jury damage is floor(difficulty/2) plus random 0–4. At difficulty above 4, give the AI an increasing chance to submit an exhibit: chance is clamp((difficulty-4)*0.13, 0, 0.9). Exhibits include “Enhanced SnackCam Image,” “Proof Facility Report,” “Jury Sentiment Scan,” “Expert Witness Bot,” and “Receipt Reconstruction,” each with absurd explanatory text. When an exhibit is used, display it in the right-side exhibit panel, increase defense damage by 5+floor(difficulty/2), increase jury damage by 4, and make the blue AI orb flash red. Otherwise make it pulse blue. If the player used “Demand proof chain,” reduce AI defense damage by 7, minimum 3, and append a line explaining that the demand slowed the attack. Add an AI rebuttal selected from sarcastic lines about crumbs, Proof Mountain, smoke accountants, sprinkles, expert bots, or unreasonable certainty. Then increment the round and deal four new random actions.

The right battle sidebar contains an exhibit panel. Initially show “No exhibits yet,” explain that higher difficulty causes photos, proof facilities, expert witnesses, and jury tricks, and show a stylized fake exhibit photo with the label “EXHIBIT.” Once triggered, replace it with the exhibit title/body and the same stylized photo. Below it show a “Jury readout” box with mood text based on jury score: at least 70, “Nodding, impressed, one juror is taking heroic notes.”; at least 52, “Interested and leaning toward reasonable doubt.”; at least 38, “Split, suspicious, still snack-motivated.”; otherwise, “The AI has them glaring at your briefcase.” Render 12 small juror faces: smiling faces for the defense portion of the jury, worried/neutral faces for the rest, with angry faces when jury is below 30. Include a “Return to docket” button.

End the case immediately with a win if AI credibility reaches 0 or jury reaches 82; lose if defense credibility reaches 0 or jury falls to 18. After round 7, if no earlier result, win when jury is at least 50 or AI credibility is lower than defense credibility, otherwise lose. Show a verdict screen with “Defense Wins” (or “Not Guilty, Somehow” at difficulty 10 or 11) and a humorous explanation, or “The AI Wins” (or “Convicted by Proof Demon” at difficulty 10 or 11) with the final jury leaning. Include buttons “Retry this case” and “Choose another case.” Add short click sounds on UI interactions. Keep the tone absurd, playful, and legal-comedy-focused while preserving the exact meters, seven-round structure, procedural three-case docket, custom argument option, escalating exhibits, and credibility/jury win conditions.
