Jelly Jungle — 3D jungle run

Build a complete browser-based 3D game called "Jelly Jungle" using Three.js with plain HTML, CSS, and JavaScript (unless the existing project already uses a framework).

Create an original arcade obstacle course inspired by colorful toy worlds and jungle playgrounds. Do NOT copy assets, characters, level layouts, or visuals from any existing game.

## Core Gameplay

- Single-player 3D obstacle course.
- Control a cute jelly-like blob character with squash-and-stretch animation.
- Third-person follow camera.
- Objective: reach the finish line as quickly as possible.

Controls:
- WASD / Arrow Keys → Move
- Space → Jump
- Shift → Dash forward with a quick jelly dive
- R → Restart from latest checkpoint

Keyboard handling — treat this as a requirement, not a detail:
- Movement is relative to the camera. Pressing forward moves the blob away from the camera,
  whatever direction the camera is currently facing. Never move along fixed world axes.
- Read `event.code`, not `event.key`, so the keys work regardless of modifiers and caps.
- `event.code` describes a physical QWERTY position, so it must not be the only mapping.
  Also accept the AZERTY letters: `KeyZ` and `KeyQ` do the same as `KeyW` and `KeyA`.
  A player on a French keyboard must be able to press either the ZQSD block or the keys
  printed W/A/S/D and move in the direction they expect.
- Arrow keys stay a full alternative to all of the above.
- Call `preventDefault()` on the movement and jump keys so the page never scrolls under the
  game.

Movement should feel:
- Responsive
- Forgiving
- Arcade-like
- Slightly bouncy
- Easy to control
- Never overly physics-based

## Level Design

Create one polished jungle course lasting around 2–3 minutes.

Sections:

### 1. Jungle Entrance
- Bright leaves
- Giant flowers
- Animated butterflies
- Wooden starting platform

### 2. Mushroom Bounce Garden
- Huge colorful mushrooms acting as trampolines
- Different bounce heights
- Floating spores particles

### 3. Sticky Slime Swamp
- Green slime pools that slow movement
- Small safe lily pads
- Bubble particles rising from slime

### 4. Swinging Vine Crossing
- Giant vines swinging back and forth
- Jump timing challenge
- Leaves fall occasionally

### 5. Rolling Fruit Hill
Large fruits continuously roll downhill:
- Watermelons
- Oranges
- Blueberries
- Pineapples

Player must dodge them while climbing.

### 6. Bubble Launch Zone
Large floating bubbles launch the player upward.

Include:
- Multiple aerial platforms
- Mid-air collectibles
- Soft landing areas

### 7. Jungle Log Bridge
A narrow wooden bridge with:
- Rotating logs
- Small gaps
- Gentle swinging motion

### 8. Flower Spinner Arena
Large spinning flowers with rotating petals that push the player away.

### 9. Giant Frog Pads
Moving lily pads that travel between ponds.

### 10. Rainbow Waterfall Finish
A colorful ramp leading into a glowing finish flower portal.

## Checkpoints

Place checkpoints throughout the course.

When activated:
- Blooming flower animation
- Color burst particles
- Pleasant sound effect (if audio is implemented)

If player falls:
- Fade out briefly
- Respawn at latest checkpoint
- Small splash particle effect

Recovery should take under two seconds.

## Character

Create an original jelly creature.

Features:
- Rounded body
- Tiny arms
- Tiny legs
- Cute face
- Large expressive eyes

- Jiggle slightly when landing
- Wobble while idle

Do not resemble Fall Guys characters.

## Obstacles

Include interactive jungle-themed obstacles:

- Bouncy mushrooms
- Swinging vines
- Rotating flowers
- Rolling fruit
- Slime puddles
- Bubble launchers
- Wind gust flowers
- Falling coconuts

Every obstacle should have smooth animation.

## Visual Style

Create a vibrant toy-like jungle.

Environment should include:

- Giant flowers
- Oversized mushrooms

- No realistic textures

Everything should feel handcrafted and playful.

- Dash
- Bounce
- Checkpoint
- Respawn
- Finish
- Falling leaves
- Floating spores
- Bubble pops

Camera effects:
- Small landing shake
- Slight FOV increase while dashing
- Smooth follow camera
- Camera lag for polished movement

## Acceptance criteria

- The project opens in a browser and plays immediately, with zero console errors.
- Every control listed above works: forward, back, left, right, jump, dash, restart —
  from the ZQSD block, from the keys printed W/A/S/D, and from the arrow keys.
- Movement follows the camera: after the camera has swung around, pressing forward still
  moves the blob away from the camera, not toward a fixed compass direction.
- The blob squashes and stretches while moving, jiggles on landing, and wobbles when idle.
- Each of the ten sections is present and reachable in one continuous run from start to
  finish.
- Every obstacle type listed moves or animates; none is decorative geometry.
- Falling respawns at the latest checkpoint in under two seconds.
- The timer, checkpoint counter and best time update correctly, and best time survives a
  restart.
