Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "SimplyUp.io - Vertical Parkour". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Vibrant, stylized "Low-poly" cartoon aesthetic. The world should feel expansive and vertical. Use a bright, gradient blue skybox to simulate a high-altitude day. * **Player Character:** A simple capsule or low-poly humanoid mesh colored in **Bright Orange** (referencing the hoodie in the screenshot). It must have a distinct "back" visual indicator so the player knows which way the character is facing. * **Level Design:** An endless vertical obstacle course constructed from geometric primitives (BoxGeometry, CylinderGeometry) acting as floating platforms. Use a mix of "urban" abstract shapes (pipes, floating crates, girders, roads in the sky). * **Mobile Optimization:** * Use `InstancedMesh` for repetitive platforms to reduce draw calls. * Limit real-time shadows to the player and immediate platforms (or use baked fake shadows/blobs). * Ensure textures are procedurally generated (colors/grid patterns) to save load time. ### 2. Audio Requirements * **BGM:** A chill, Lo-Fi Hip Hop track or relaxing ambient synth music to counterbalance the frustration of falling. It should loop seamlessly. * **Sound Effects (SFX):** * **Jump:** A satisfying "whoosh" or "spring" sound. * **Landing:** A solid "thud" with varying intensity based on fall height. * **Wind:** A dynamic wind whistling sound that increases in volume/pitch as the player gets higher in the Y-axis. * **Fall:** A descending whistle effect when the player slips off a platform. ### 3. Gameplay Loop * **Core Mechanic:** The player starts at the bottom (`y=0`). The goal is to jump from platform to platform to reach the highest possible altitude. * **Physics & Challenge:** Implement a custom physics controller (non-floaty). The jump should feel precise and tight. There are **NO checkpoints**. If the player misses a jump, they fall. If they hit the ground (y=0), the run resets (or they have to climb all the way back up). * **Scoring:** A "Height Meter" UI at the top center showing the current altitude (e.g., "120m"). * **Victory/Failure:** There is no distinct "win" screen, it is an endless high-score run. The failure state is falling, accompanied by a screen shake effect upon hitting the ground. ### 4. Mobile Controls & Interaction * **Orientation:** Force **Landscape Mode** for better peripheral vision of the parkour route. * **Touch Controls (Dual-Zone Layout):** * **Left Half Screen:** Invisible Virtual Joystick for movement (WASD equivalent). Dragging moves the character relative to the camera view. * **Right Half Screen:** Touch & Drag to rotate the camera (OrbitControls logic, but locked behind the player). * **Action Button:** A large, semi-transparent circular button (at least 64x64px) in the bottom-right corner (overlapping the camera zone slightly) for **JUMP**. * **Feedback:** * Add `navigator.vibrate(20)` on jump initiation. * Add a heavier vibration `navigator.vibrate(50)` when landing from a high jump. * **Camera:** Implement a Third-Person Camera with collision detection (so it doesn't clip through walls) that smoothly follows the player. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

SimplyUp.io is a thrilling competitive multiplayer parkour game that challenges players to race upward through an endless vertical world. This 3D climbing adventure puts your jumping skills to the ultimate test, where precision timing and steady nerves are the only things standing between you and a devastating fall.

In this unforgiving parkour challenge, there are no safety nets, no checkpoints, and no second chances. One mistimed jump sends you plummeting back to the starting line, making every leap a heart-pounding decision that could make or break your climb to the top.

Core Features

SimplyUp.io delivers an authentic parkour experience that separates the skilled from the fallen:

Competitive Multiplayer Racing

Race against friends and strangers from around the world in real-time. Watch other players attempt the same treacherous climbs while you push yourself higher and higher up the endless tower.

No Checkpoint System

The game's most defining feature is its complete lack of checkpoints. Fall once, and you start over from the bottom. This creates intense moments where every jump becomes a calculated risk with potentially devastating consequences.

Endless Vertical World

The climbing challenge never ends. The tower stretches infinitely upward, presenting new obstacles and increasingly difficult jumps as you progress. How high can you climb before gravity claims its victory?

Precision-Based Gameplay

Success depends entirely on your skill, timing, and spatial awareness. The simple controls hide the complex challenge of mastering momentum, distance calculation, and split-second decision making.

3D Parkour Environment

Navigate through beautifully rendered 3D environments with realistic physics that make every jump feel authentic and every fall genuinely consequential.

Game Mechanics

The beauty of SimplyUp.io lies in its elegant simplicity. The core gameplay revolves around three fundamental elements:

Movement and Positioning : Use precise movement to position yourself for each jump. Every step matters when there's no room for error.

Jump Timing : Master the art of timing your jumps perfectly. Too early or too late, and you'll find yourself falling back to square one.

Risk Assessment : Constantly evaluate whether to attempt risky jumps for faster progress or take safer routes that may cost you the race.

Operation Guide

SimplyUp.io features intuitive controls that anyone can learn but few can master:

  • WASD or Arrow Keys : Move your character forward, backward, and sideways
  • Mouse Movement : Look around to assess your surroundings and plan your next move
  • Spacebar : Jump - the most important control in the game

The key to success lies not in complex button combinations, but in mastering the timing and precision of these simple inputs. Every movement should be deliberate, every jump calculated.
