Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Hoppenhelm - Dungeon Hopper**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** **Low-poly 3D with a Toon/Cel-Shader**. The aesthetic should mimic the provided 2D vector art: bold black outlines around models, flat vibrant colors, and minimal gradients. * **Main Character (Sir Hoppenhelm):** A chibi-proportioned knight composed of simple geometric shapes (box/cylinder armor). He must have a floating visor (visor separate from helmet body for cartoon effect), a short sword, and a large rectangular shield. Primary colors: Steel Blue armor, Purple/Pink rim lighting accents. * **Environment (Dungeon):** * **Perspective:** Isometric or Orthographic camera view, tilted slightly to show depth but maintain a clear grid layout. * **The Grid:** The floor consists of individual stone tiles floating in a void. Some tiles are cracked (crumble after 1 second), some have spikes (trap), and some contain coins. * **Background:** A deep, royal purple fog or gradient background (matching the screenshot) to obscure the bottom of the pit. * **Lava:** A rising plane of orange/red glowing lava that constantly moves upward/forward, forcing the player to keep moving. * **Mobile Optimization:** Use simple geometries (BoxGeometry, CylinderGeometry) to keep the polygon count extremely low. Use a single texture atlas if possible, or basic materials with Vertex Colors to save on load times. ### 2. Audio Requirements * **BGM:** A fast-paced **Chiptune / 8-bit Medieval track**. It should feel heroic but urgent (120-130 BPM). * **Sound Effects (SFX):** * **Hop:** A cute "spring" or mechanical "clank" sound on every jump. * **Attack:** A retro 8-bit "swish" noise. * **Shield:** A metallic "ding" or "clang" when blocking a projectile. * **Lava:** A low-frequency bubbling/sizzling loop. * **Coin:** A high-pitched, satisfying arcade "bling". ### 3. Gameplay Loop * **Core Mechanic:** The game is a **turn-based reaction runner**. The player is on a linear (or 3-lane) grid of tiles. * **The Tick:** The game moves to a rhythm. The lava rises constantly. * **Actions:** * **Jump:** Moves the knight one tile forward. * **Attack:** Destroys an enemy standing on the next tile. * **Shield:** Blocks a projectile or hazard (like spikes) on the current or next tile. * **Obstacles:** * **Slimes/Bats:** Block the path; must be Attacked. * **Spikes:** Extend/retract on a timer; must be Blocked or timed correctly. * **Crumbling Tiles:** Disappear shortly after landing. * **Win/Loss:** * **Loss:** Falling into lava, being hit by an enemy without attacking, or landing on spikes without shielding. * **Score:** Based on distance traveled (tiles hopped) + coins collected. ### 4. Mobile Controls & Interaction * **Screen Orientation:** **Portrait Mode** (Vertical) is mandatory to allow for one-handed play and a clear view of the path ahead. * **Touch Controls (The "Thumb Zone"):** * Create a dedicated HTML/CSS UI overlay at the bottom 25% of the screen. * **Three Big Buttons:** 1. **Left Button (Icon: Sword):** Triggers Attack. 2. **Center Button (Icon: Shield):** Triggers Block/Wait. 3. **Right Button (Icon: Boot/Arrow):** Triggers Jump (Forward). * *Alternative Gesture Support:* Swipe Right to Jump, Tap to Attack, Swipe Down to Shield. * **Feedback:** * **Haptic Feedback:** Trigger `navigator.vibrate(50)` on taking damage or hitting an enemy. * **Visual Juice:** When an action is pressed, the button should visually depress. On killing an enemy, spawn simple particle explosions (cubes). Screen shake slightly on taking damage. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About Game

Hoppenhelm is a thrilling casual adventure platformer that combines medieval knight action with challenging dungeon exploration. As Sir Hoppenhelm, you find yourself trapped in the depths of your own castle's dangerous dungeons, where survival depends on quick reflexes and strategic timing. The game features a unique "the floor is lava" mechanic that keeps players constantly moving and adds intense excitement to every moment.

This charming adventure game appeals to players who enjoy classic platforming action with a medieval twist. The colorful cartoon art style makes it accessible to all ages while maintaining engaging gameplay depth that keeps experienced gamers coming back for more.

Core Features

Dynamic Lava Floor Mechanics

The most distinctive feature of Hoppenhelm is its real "floor is lava" gameplay. Unlike traditional platformers, staying in one place too long means certain doom. This creates a unique rhythm where players must constantly plan their next move while managing combat and collection objectives.

Character Progression System

Collect coins and treasures throughout your adventure to upgrade Sir Hoppenhelm's abilities. Make your knight stronger, bouncier, and more capable of handling the castle's deadly challenges. The progression system adds depth and replayability to the core jumping mechanics.

Unlockable Content

Discover new allies with unique special abilities that change how you approach each dungeon level. Additionally, unlock powerful new weapons that give Sir Hoppenhelm different combat options against the dangers lurking in Dunkelburg Castle.

Precision-Based Combat

Master a simple yet effective three-action combat system. Attack enemies with your sword, defend against incoming threats with your shield, and time your jumps perfectly to navigate treacherous terrain. Each action requires careful timing and strategic thinking.

Gameplay Mechanics

Hoppenhelm challenges players to ascend through multiple dungeon levels while managing three core mechanics simultaneously. The lava floor constantly rises, forcing continuous upward movement. Enemies patrol the dungeons, requiring combat skills to defeat. Coins and treasures are scattered throughout each level, rewarding exploration and risk-taking.

Success requires balancing speed with caution. Moving too quickly might cause you to miss valuable coins or fall into traps. Moving too slowly means the lava will catch up. This creates a perfect tension that makes every playthrough exciting and unpredictable.

Operation Guide

The game uses an intuitive three-key control scheme designed for maximum accessibility:

  • Left Arrow Key : Attack with your sword to defeat enemies and break obstacles
  • Right Arrow Key : Jump to navigate platforms and avoid the rising lava
  • Up Arrow Key : Raise your shield to block enemy attacks and projectiles

Master the timing of these three actions to become an unstoppable dungeon escape artist. The key to success is learning when to attack, when to defend, and when to make that crucial jump to safety.

Pro Tips for Success

  • Keep moving constantly - suspicious tiles often collapse or trigger traps
  • Collect every coin possible to maximize your upgrade potential
  • Learn enemy attack patterns to time your shield blocks perfectly
  • Don't be greedy - sometimes it's better to skip a coin than risk the lava
