Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Just One Boss - Retro Arcade Battle**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Pixel Art aesthetic constructed in a 3D space. The perspective should be a fixed orthographic camera looking slightly down (tilted) at the arena to give depth while maintaining the 2D pixel look. * **Color Palette:** High contrast neon-retro colors against a deep void background. Dominant colors: Deep Indigo (Background), Cyan (Player), Gold/White (Boss), Glowing White (Damage Tiles), Red (Danger/Attacks). * **Player Character:** A simple, cute blue slime/cube entity. It should have a subtle "squash and stretch" animation effect when moving or changing direction to simulate soft body physics. * **The Boss:** A large, floating, multi-part entity (Head with a top hat, detached floating hands holding a wand). The boss should bob and weave at the top of the screen. * **The Arena:** A grid-based floor (e.g., 8x5 or similar) floating in space. The floor tiles are dark blue by default. * **Visual Feedback:** * **Damage Tiles:** Certain floor tiles must glow bright white randomly. * **Attack Indicators:** Warning overlays (red flashing tiles or crosshairs) on the floor *before* the boss strikes. * **Particles:** Pixelated explosion particles when the player hits a white tile (damaging the boss) or gets hit. * **Mobile Optimization:** Use `THREE.BoxGeometry` and `THREE.PlaneGeometry` with pixel-art textures for efficiency. Avoid complex meshes. Use simple glowing shaders for the active tiles. ### 2. Audio Requirements * **BGM:** A fast-paced, quirky, chiptune/8-bit track. It should feel tense but fun, similar to classic NES boss battle themes (high BPM, square waves, fast arpeggios). * **Sound Effects (SFX):** * **Move:** A soft, high-pitched "blip" or squishing sound. * **Damage Dealt:** A crunchy, satisfying 8-bit "crash" or "power-up" sound when touching a white tile. * **Damage Taken:** A low-pitched "thud" or "buzz" error sound. * **Boss Laugh/Phase Change:** A distinct, echoing synthesized sound effect. ### 3. Gameplay Loop * **Objective:** Deplete the Boss's health bar to zero while surviving endless waves of attacks. * **Player Movement:** The player moves strictly on the grid (up, down, left, right). Movement is snappy and grid-aligned (not continuous physics-based sliding). * **Boss Mechanics:** * **Phases:** The boss cycles through different attack patterns (e.g., shooting projectiles, sweeping laser beams across rows/columns, dropping bombs on specific tiles). * **Vulnerability:** The boss is invulnerable to direct attacks. * **Scoring/Damage Mechanic:** * Random tiles on the grid light up **White**. * The player must step on these White tiles to "launch" an attack at the boss, reducing the boss's HP. * After being stepped on, the tile deactivates, and a new one lights up elsewhere. * **Lose Condition:** The player has limited HP (e.g., 3 hearts). Getting hit by a boss attack removes a heart. Zero hearts = Game Over. ### 4. Mobile Controls & Interaction * **Orientation:** **Portrait Mode** is preferred for one-handed play, or **Landscape** with distinct control zones. (Let's target **Portrait** for this arcade feel). * **Control Scheme (Virtual D-Pad):** * Implement a large, semi-transparent Virtual D-Pad at the bottom center of the screen. * Alternatively, support **Swipe Gestures**: Swipe Up/Down/Left/Right anywhere on the screen to move the slime one grid space in that direction. This feels more natural for mobile grid-based games. * **UI Layout:** * **Top:** Boss Health Bar (prominent, spans width). * **Top Corners:** Player Health (Hearts). * **Center:** The Gameplay Arena. * **Bottom:** Control Area (invisible touch zone or D-Pad visual). * **Haptic Feedback:** Trigger a short vibration (`navigator.vibrate(50)`) when the player takes damage or successfully hits the boss. * **Start/Restart:** A large, easy-to-tap "START" button overlay before the game begins and after Game Over. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
