Please use Three.js to generate a **mobile-first game** with the theme "**Heart Surgery Simulator 3D**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Stylized "Medical Realism". Use a slightly cartoonish, vibrant color palette (deep reds for organs, stark whites for bones, sterile blues for drapes) to match the reference image but rendered in 3D. The style should be reminiscent of *Surgeon Simulator* but optimized for mobile WebGL. * **Camera Perspective**: Fixed Top-Down First-Person (Surgeon's POV). The camera should look directly down into the patient's chest cavity. * **Key Models**: * **Patient Torso**: Covered mainly by a blue sterile drape, with an aperture (opening) revealing the chest skin. * **Ribcage**: Individual low-poly rib meshes that can be interacted with (cracked/removed) separately. * **The Heart**: A pulsing 3D model (use vertex shader scaling or morph targets for heartbeat animation). * **Surgical Tools**: Models for Scalpel, Rib Spreader, Bone Cutter, and Tweezers. * **VFX**: * **Blood Particles**: Simple red particle sprites that emit when cutting or making mistakes (essential for the "Gross" tag). * **Dynamic Textures**: Ability to draw red lines on the skin texture to simulate an incision. * **Performance**: Use simple geometry for organs (spheres/capsules deformed). Use baked lighting for the operating room ambience to save GPU resources. ### 2. Audio Requirements * **BGM**: None or a low-hum ambient drone (hospital AC sound) to increase tension. * **SFX (Crucial for feedback)**: * **Heart Monitor**: A rhythmic "Beep... Beep..." that speeds up if the player makes a mistake and flatlines (continuous tone) on failure. * **Surgical Sounds**: Wet "squish" sounds when touching organs. A sharp "snap/crunch" sound when using the bone cutter on ribs. Metallic "clink" when picking up tools. * **UI Sounds**: Clean digital blips for selecting tools. ### 3. Gameplay Loop The game simulates a simplified heart transplant procedure in stages: 1. **Incision**: Player selects the Scalpel and must trace a dotted line on the chest skin. Accuracy is scored. 2. **Bone Breaking**: Player selects the Bone Cutter. They must tap specific weak points on the ribs to crack them. 3. **Exposure**: Player uses the Retractor to widen the ribcage (drag gesture). 4. **The Surgery**: * The heart beat is irregular. The player must extract the old heart (drag out) and place a new donor heart (drag in) within a time limit. * *Risk*: If the player touches the surrounding lungs or hits a rib while moving the heart, the "Blood Level" rises. 5. **Win/Loss**: * **Win**: Successfully placing the new heart and stabilizing the heart rate. * **Loss**: Patient bleeds out (blood bar fills up) or heart stops completely before replacement. ### 4. Mobile Controls & Interaction * **Primary Input**: **Raycaster-based Touch**. The game must detect touch/mouse positions on the 3D models accurately. * **Gestures**: * **Tap**: To break bones or select tools. * **Drag/Swipe**: To guide the scalpel along a path or to move organs (drag and drop mechanics). * **Tool Selection UI**: A bottom-aligned horizontal dock containing large, thumb-friendly icons (64x64px minimum) for switching tools (Scalpel, Cutter, Hand, Tweezer). * **Feedback**: * **Haptic**: Trigger `navigator.vibrate(50)` when a rib snaps or a mistake is made. * **Visual**: The tool model should follow the user's finger/cursor with a slight lerp (lag) to simulate weight. * **Orientation**: Locked to **Portrait Mode** for one-handed playability, emphasizing the vertical nature of the human torso.
