Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Jump Only - Vertical Ascent Challenge**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Create a vibrant, clean **2.5D aesthetic** (3D models on a 2D plane). Use a "Flat Design" approach with soft gradients and bold colors similar to the reference image. * **Character:** The player controls a cute, white, soft-body blob (use a distorted `SphereGeometry` or capsule). It should have a simple face (two slanted angry eyebrows `BoxGeometry` and a small mouth) to convey determination. * *Trail Effect:* Implement a `TrailRenderer` or a particle system that leaves a translucent green path behind the character as it jumps, mimicking the "swoosh" effect in the reference. * **Obstacles:** * **Spikes:** Sharp, triangular prisms (`ConeGeometry` with 3 radial segments) colored in hot pink (`#FF007F`). * **Saw-blades:** Rotating metallic disks with serrated edges, spinning constantly. * **Platforms:** Minimalist rectangular blocks. Some should be static, others moving horizontally. * **Background:** A deep, dark blue gradient (`#1a1a40` to `#0d0d26`) to make the pink spikes and white character pop. * **Mobile Optimization:** Use simple geometries (Low-poly) and basic materials (`MeshLambertMaterial` or `MeshToonMaterial`) to ensure high frame rates on mobile devices. Avoid complex shadows; use baked lighting or a simple directional light. ### 2. Audio Requirements * **BGM:** A high-tempo, catchy **Synth-pop or Chiptune track** (120-140 BPM) to match the "Arcade" and "Skill Game" vibe. It should feel energetic but not annoying, encouraging the player to keep trying. * **SFX:** * **Jump:** A short, ascending synthesizer "whoosh" or "bloop" sound. Distinct sounds for Left Jump vs. Right Jump (slightly different pitch). * **Death:** A "crunch" or digital disintegration sound when hitting spikes. * **Win/Level Up:** A cheerful major-chord jingle. * **UI:** Soft clicks for menu buttons. ### 3. Gameplay Loop * **Core Mechanic:** The character constantly bounces slightly in place (idle animation). The ONLY movement is jumping diagonally upward. * **Left Input:** Character jumps up and to the left. * **Right Input:** Character jumps up and to the right. * *Note:* There is no walking. Gravity is strong, making the game fast-paced. * **Goal:** Ascend vertically through a platforming course to reach the "Finish Line" (a glowing portal or flag) at the top. * **Hazards:** Touching any spike, saw-blade, or falling off the bottom of the screen results in immediate failure and resets the level instantly (fast restart loop is crucial for "difficult games"). * **Progression:** The game should generate a vertical level layout. As the player goes higher, the background hue could shift slightly (e.g., Blue -> Purple) to indicate progress. ### 4. Mobile Controls & Interaction * **Screen Orientation:** **Portrait Mode (Vertical)** is preferred to emphasize the vertical ascent gameplay. * **Touch Controls:** Split the screen vertically into two invisible touch zones: * **Left Half of Screen:** Tap to Jump Left. * **Right Half of Screen:** Tap to Jump Right. * **UI Layout:** * **Pause Button:** Top-right corner (min 44x44px touch area). * **Level Progress:** A thin progress bar on the side or top indicating height relative to the finish line. * **Death Screen:** Must have a large, thumb-friendly "Retry" button centered on the screen. * **Feedback:** * **Haptic Feedback:** Trigger a short vibration (`navigator.vibrate(10)`) upon landing a jump and a stronger vibration (`navigator.vibrate(50)`) upon death. * **Visual Feedback:** The character should squash and stretch slightly upon jumping and landing to give a "jelly" physical feel. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
