Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Oh, flip!**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Extremely minimalistic, vibrant "Hyper-casual" aesthetic. Use simple geometric primitives (cubes, planes) with solid, saturated colors. No textures; rely on flat shading or simple Lambert materials. * **Main Character:** An orange rectangular block (representing the body) with a single large "cyclops" eye (white sclera, black pupil) centered on its face. It has two simple black rectangular legs attached to the bottom. * **Environment:** * **Ground:** A bright green infinite plane. Add a thick black line running horizontally across the screen to serve as the "ground level" visual guide. * **Background:** A solid light blue sky (#A0D8EF). * **Camera:** Orthographic camera side-view (2D platformer perspective), locked to follow the character's horizontal movement but with slight smoothing. * **Performance:** Keep geometry count extremely low (Low-poly). Use object pooling for any particle effects (e.g., small dust clouds when landing). ### 2. Audio Requirements * **BGM:** A quirky, upbeat, and repetitive chiptune or synthesized loop. Think "silly physics game" vibes—light percussion and a bouncy melody. * **SFX:** * **Jump Charging:** A rising pitch whistle or spring-loading sound while the screen is pressed. * **Release/Jump:** A "Boing!" or cartoon spring sound. * **Rotation:** A "Whoosh" air-cutting sound as the block spins. * **Perfect Landing:** A satisfying "Ding!" or high-pitched "Pop!". * **Fail/Crash:** A dull thud or a comedic "womp-womp" sound when landing on the head/face. ### 3. Gameplay Loop * **Core Mechanic:** The player controls the orange block character. * **Input (Hold):** The character crouches (squashes vertically), charging up potential energy. The longer the hold, the higher the jump (capped at a max value). * **Input (Release):** The character launches into the air and automatically begins rotating backward (backflip). * **Objective:** Land on feet (the black legs) to score points. * The goal is to move forward as far as possible by chaining jumps. * **Physics:** * Implement 2D physics (using Cannon.js or a simple custom verlet integration) restricted to the X/Y plane. * Rotation speed should be constant or dependent on the jump force. * Gravity needs to feel slightly "heavy" to make timing the landing challenging. * **Win/Loss:** * **Success:** Landing upright (within a tolerance angle, e.g., +/- 30 degrees). * **Failure:** Landing on the face (eye) or back triggers a "Game Over" state, requiring a restart tap. ### 4. Mobile Controls & Interaction * **Control Scheme:** "One-Button" gameplay. * **Touch Start / Mouse Down:** Begin charging the jump (squash animation). * **Touch End / Mouse Up:** Release to jump. * **Screen Orientation:** Landscape mode preferred, but responsive UI should handle Portrait by zooming out the Orthographic camera to maintain the field of view. * **UI Elements:** * **Score:** Large, white, bold sans-serif font centered at the top of the screen. * **Restart Button:** An overlay that appears on death with a large "Replay" icon (minimum touch target 60x60px). * **Feedback:** * **Visual:** When charging, the character mesh should visibly scale down on the Y-axis and widen on the X-axis (squash). On release, it stretches (stretch). * **Haptic:** Trigger a light vibration (using `navigator.vibrate`) upon a successful landing and a heavy vibration upon crashing. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

Play seamlessly across all devices! Whether you're on a desktop computer, laptop, tablet, or smartphone, Oh, flip! runs perfectly in your web browser without any downloads or installations required.

Gameplay Mechanics

The core gameplay revolves around timing and physics mastery. Your orange square character stands ready to perform spectacular backflips, but success depends entirely on your ability to time your clicks perfectly. Too early or too late, and you'll find your character tumbling ungracefully to the ground.

The game's physics engine calculates realistic rotation, momentum, and landing mechanics, making each attempt feel authentic. As you progress, you'll develop an intuitive sense for the perfect timing needed to execute flawless backflips consistently.
