Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Topsy Turvy". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: "Hand-drawn 2.5D". The game should look like a living doodle. Use a warm, peach/salmon colored background (`#FFCC99`) to match the original game's aesthetic. * **Player Character**: A cute, simple white sphere or capsule with "stick figure" limbs (use `Three.Group` to assemble primitives). The character should have a thick black outline effect (using `Three.EdgesGeometry` or a shader) to mimic a drawing. * **Environment Geometry**: * **Platforms**: Deep black (`#1A1A1A`) silhouettes with rough, jagged edges. Instead of perfect rectangles, add slight noise to the vertices or a displacement map to make them look hand-sketched. * **Obstacles**: Sharp, triangular spikes (black) placed on surfaces. * **Goal**: A swirling, spiral portal particle effect using bright cyan or white particles. * **Camera Perspective**: Orthographic camera locked to a side-scrolling view, but slightly angled to show depth (2.5D). The camera must rotate *with* the player when gravity changes. * **Mobile Optimization**: Use simple materials (`MeshLambertMaterial` or `MeshToonMaterial`). Limit shadow casting to the main character only. ### 2. Audio Requirements * **BGM**: A quirky, pizzicato-heavy orchestral track. Think "curious and clumsy." It should be looping and unobtrusive. * **Sound Effects (SFX)**: * **Movement**: Soft, scribbly "pencil-on-paper" sounds when walking. * **Gravity Shift**: A "woosh" or "slide" whistle sound when the world rotates. * **Jump**: A cute "hup!" or cartoon spring sound. * **Portal Entry**: A magical, rising chime sound indicating success. * **Death**: A comedic "record scratch" or a soft thud followed by a "wah-wah" trumpet. ### 3. Gameplay Loop * **Core Mechanic**: **Surface-Based Gravity**. The player moves using a virtual joystick. When the player walks towards a vertical wall that connects to the floor (a 90-degree inner corner), the game treats that wall as the new "floor." * *Technical implementation*: Raycast downwards from the player's local feet. Align the player's "up" vector with the surface normal of the platform they are standing on. * *Camera Transition*: When gravity shifts, the entire camera/world view should smoothly rotate 90 degrees so the player always feels like they are standing upright. * **Objective**: Navigate a maze-like level of twisting black platforms to reach the Portal. * **Hazards**: Touching spikes or falling off the screen (into the "sky") resets the level. ### 4. Mobile Controls & Interaction * **Control Scheme**: Landscape orientation. * **Left Screen**: Virtual Joystick (Floating) for movement (Left/Right relative to current gravity). * **Right Screen**: A circular "Jump" button (44px+ hit area) with a simple arrow icon. * **Touch Feedback**: * Visual: The joystick should show a ring indicating touch position. * Haptic: Trigger a short vibration (`navigator.vibrate(10)`) when landing a jump or shifting gravity. * **UI Layout**: Minimalist. Level counter in the top-left. A "Restart" button in the top-right (away from jump controls). * **Responsiveness**: Physics must be snappy. No "floaty" jumps. The character should stop immediately when the joystick is released. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Topsy Turvy is an innovative puzzle-platformer that challenges your perception of gravity and space. When Topsy discovers a mysterious portal, his world literally turns upside down - walls become walkable surfaces, and gravity follows wherever your feet land. This creative twist on traditional puzzle mechanics creates a uniquely engaging experience that will test your spatial reasoning and problem-solving skills.

With its charming art style and intuitive gameplay, Topsy Turvy offers a refreshing take on the puzzle genre that's both accessible to newcomers and challenging enough for experienced puzzle enthusiasts.

Core Features

Revolutionary Gravity Mechanics

The game's standout feature is its gravity-shifting gameplay. Unlike traditional platformers where gravity always pulls downward, Topsy Turvy allows you to walk on any surface - walls, ceilings, and floors all become navigable terrain. This mechanic transforms every level into a three-dimensional puzzle where spatial awareness is key.

Charming Visual Design

Featuring a cute, minimalist art style with warm colors and friendly character design, the game creates an inviting atmosphere that makes even the most challenging puzzles feel approachable. The visual clarity helps players focus on the puzzle mechanics without distractions.

Progressive Difficulty

Each level introduces new challenges and variations on the core gravity-shifting concept. From simple navigation puzzles to complex multi-portal challenges, the game gradually builds complexity while maintaining its core appeal.

Game Mechanics

Portal Navigation

The central objective is guiding Topsy through various portals scattered throughout each level. These portals serve as both obstacles and solutions, requiring players to think creatively about how to reach them using the gravity-shifting mechanics.

Spatial Puzzle Solving

Success requires visualizing the level from multiple perspectives. What appears to be an insurmountable wall might become a pathway when you shift your approach and utilize the gravity mechanics effectively.

Controls & Operation

Desktop Controls: - Arrow Keys : Move Topsy in four directions - Spacebar : Advance to the next level after completing current puzzle - Mouse : Navigate menus and interface elements

Mobile Controls: - Touch Controls : Tap and swipe to move Topsy - On-screen buttons : Access menu options and level progression

The control scheme is intentionally simple, allowing players to focus entirely on solving the spatial puzzles rather than struggling with complex input combinations.
