Cosmic Check

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.

Create a browser-based Three.js cinematic cutscene called “Cosmic Check,” not a conventional interactive game. It is a seamless 5-second looping animation on a timeline labeled 00:11–00:16 at 24 fps, with a dark space background and a dramatic anime-inspired chess confrontation. Use a perspective camera that begins fairly wide above and in front of the scene (around position 0, 5.8, 10.5), then smoothly pushes in toward the board and queen, ending around (-1.9, 3.15, 5.25), while continuously looking at the center/queen area. Render with antialiasing, soft shadows, ACES-style tone mapping, purple fog, and a very dark violet background filled with many tiny white stars.

The central set is a floating round violet table/platform, supporting a square 8x8 chessboard made of alternating deep purple-black and pale lavender squares, each slightly raised, with a thick violet rectangular frame. Include stylized chunky cel-shaded chess pieces with black ink-like outlines: pale pawns on one side, dark purple pawns on the opposite side, four corner rook-like pieces, and one prominent purple queen. The queen should have a short cylindrical chess-piece body, broad base, faceted/octagonal purple top, gold halo ring, purple emissive glow, translucent additive aura sphere, and a ring of bright purple anime power spikes that become visible late in the clip.

Place two original cat-like deity rivals opposite each other around the floating board. They are stylized low-poly/cel-shaded humanoid cats with thick dark outline silhouettes, slim robed bodies, long necks, angular cat heads, tall pointed ears, narrow eyes with glowing pupils, sharp eyebrows, small muzzle, cheek marks, smug mouth, gold collar/sash and waist ring, gold shoulder guards, arms posed toward the board, small claw tips, curled tail, and translucent flame-like aura elements. The left rival is violet-skinned with a dark blue robe and gold accents, positioned at the back-left of the table and facing inward; the right rival is pale blue with a reddish-brown robe and cyan accents, positioned opposite and facing inward. Give both subtle breathing/bobbing animation and ear flicks. During the queen move, animate the left rival’s right arm reaching/gesturing toward the board and gradually deepen its smirk; animate the right rival with a small startled/panicked reaction.

Timeline behavior: for roughly the first 1.35 seconds, hold the queen at its home square near the far side of the board. From about 1.35 to 2.3 seconds, smoothly move the purple queen diagonally across the board toward the near-left/center square (from approximately x=.31,z=-2.17 to x=-.93,z=-.93), with a tiny floating/bobbing motion and slight rotation. Every 0.5 seconds (12 frames), move a rotating selection of non-queen pieces by only about 0.05 board units in one of four directions, make the selected piece briefly scale/pop larger, then ease it back home; synchronize each with a chess clack and a visual string-note pluck. Around the 00:15 point (about 4 seconds into the clip), trigger a dramatic queen power cue: show the queen glow spike, brighten its point light, expand/pulse its aura and gold halo, reveal and rotate the 12 radial purple spikes, increase the purple rim light, and briefly enlarge the queen. Also show golden/purple radial anime speed lines around the queen and keep them pulsing through the end. The left rival’s smirk and the right rival’s panic reaction should become visibly emphasized around this cue.

Add a playful math-fantasy visual layer: place floating glowing sprite glyphs around the board/table, including “×2”, “π”, “√”, “+7”, “Σ”, “÷”, “=”, and “△”, colored alternately cyan and yellow, gently bobbing and slowly orbiting. Add a small musical string-stave overlay at the top made from several thin luminous vertical notes; every 12 frames briefly animate one note as if plucked. Use procedural Web Audio after the user interacts: short staccato sawtooth plucks with a repeating set of pitches such as 392, 466, 523, 622, and 784 Hz, plus brief triangle-wave chess clacks on each piece movement. Include a Music On/Music Off button.

HUD/UI should be chunky, readable, and overlaid on the canvas. At the top center show the large uppercase title “COSMIC CHECK” in white with a violet glow. Under it show “00:11–00:16 · 24fps timeline · 82% cosmic battle-anime · 18% playful math-fantasy.” Show a timecode panel at bottom-left with the current 00:11.xx–00:16.xx time and frame number, in tabular numerals, with a dark translucent purple gradient, rounded corners, and a gold border. At the bottom-right provide pill-shaped purple gradient buttons labeled “Download Video,” “Replay cutscene,” and “Music On” (switch to “Music Off” when toggled). Download Video should use canvas.captureStream and MediaRecorder to export the current five-second animation, including audio when enabled, preferably WebM and MP4 if supported, and name the file cosmic-check-00-11-00-16. Show recording/download status text. Add a centered bottom explanatory note: “Original homage scene — cel-shaded cosmic cats, power aura, 24fps timecode cues, and math-rune board. Use Download Video to export the 5-second clip.” Around the 00:15 cue, display small overlay badges reading “😼 Smirk cue,” “💧 Rival panic,” and “00:15 · queen glow spike.” Keep the whole presentation responsive to viewport resizing, with a compact layout for short screens.
