Part 1: the game Claude Sonnet 5.5 in Claude Code

  1. Create a 3D animation using HyperFrames and Three.js for a cartoon kart racing intro, a game motion graphics trailer.
  2. Make it a 2.5D cartoon, 3D-ish game.
  3. It needs improvement on the hands holding the wheel.
  4. Also add a fully playable stage demo.
  5. You can do better in terms of graphics. We need chunky, colourful cartoon characters.
  6. We need a way to turn this into a game ready for Android.
  7. Car selector with powers.
  8. Fix the stadium collisions, and the arrival.
  9. The Blaze character has only one eye. Kinda scary.
  10. Adapt the game to the D-pad remote and push it to my Sony Bravia TV as an APK.
  11. Make it easy and fun to play with the TV remote, for kids.
  12. Add Bluetooth controller pairing and split screen.

Part 2: making it fun to play Claude Opus 5.5 in Claude Code

  1. On the TV it plays alone. Fix the split screen: pick players and detect the gamepads.
  2. Add an easy mode for solo play. It is too easy to hit the sides.
  3. Let each player pick a character with their own remote or gamepad, coloured differently.
  4. Add a gamepad tutorial. Easy buttons: triggers to drive, X for a nitro boost.
  5. Make the cars able to jump and fly over ramps.
  6. Add cool background music and sound effects with Lyria.
  7. Add more tracks. Use Codex to generate the images.
  8. Make it playable online with gamepads and split screen, on Mac and Windows.

The music Lyria 3 Pro, $0.08 per call

  1. RACEUpbeat cartoon kart racing video game music, instrumental only, no vocals. Fast 150 BPM in E major, punchy drums, slap bass, bright synth lead and brass stabs, playful and energetic like a family party racing game. No intro, no breakdown and no ending, so it loops seamlessly.
  2. MENUCheerful video game character-select menu music, instrumental only, no vocals. 118 BPM in G major, bouncy bass, marimba and funky guitar, light drums, friendly and exciting for kids. No intro, no breakdown and no ending, so it loops seamlessly.
  3. SFXSound effects library recording for a video game. No music, no melody, no rhythm, no vocals, no background ambience. 4 isolated variations of the same sound effect, each separated by three seconds of total silence: a cartoon go-kart jumping off a ramp, a quick springy boing with a rising whoosh. (Same for the landing thud and the nitro whoosh.)

The art Codex image generation, from screenshots of the game

  1. Recreate these four characters and karts faithfully (same colours, same chunky low-poly cartoon style with thick black outlines) as a cinematic movie-opening shot: all four karts lined up on the starting grid under a big checkered start arch, cheering grandstands, pine trees, blue sky, confetti. Joyful and family friendly. No text anywhere.
  2. Three track concept images in the same style, wide roads with jump ramps and item boxes, no text: Candy Canyon (candy hills, lollipop trees, a chocolate river), Snowy Peaks (icy road, snowmen, northern lights, ice arches), Beach Bay (sandy road by a turquoise sea, palm trees, a lighthouse at sunset).
