Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Johnny Upgrade". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Side-Scroller using a **Low-Poly Toon/Cel-Shaded** aesthetic to mimic the original Flash cartoon style. Use `MeshToonMaterial` with bright, saturated colors (Primary Red for the hero, Industrial Grays/Greens for enemies). * **Key Characters:** * **Hero (Johnny):** A blocky, stylized superhero character in a red bodysuit, yellow belt, and blue visor. Start with a simple boxy humanoid rig. * **Enemy (Robot Boss):** A tank-treaded robot with a green chassis and spikes (represented by cones) on the back. * **Environment:** Modular sci-fi platform tiles (metal grates, caution stripes). A simple gradient skybox (orange-to-yellow). * **Mobile Optimization:** Use instanced rendering for platform tiles. Limit distinct draw calls. Texture resolution should be low (512x512 max) or use vertex colors to save memory. Camera fixed to a side view (OrthographicCamera preferred for the classic feel). ### 2. Audio Requirements * **BGM:** A looping, high-energy **8-bit / Chiptune** track that starts slow and gets faster as the player upgrades their speed. * **Sound Effects (SFX):** * **Interaction:** A satisfying "Ka-ching" or retro coin sound for collecting currency. * **Movement:** A cartoon "Boing" for jumping. * **Failure:** A "Power Down" whistle/groan sound when the timer runs out. * **UI:** Crisp "blip" sounds for clicking upgrade buttons in the shop. ### 3. Gameplay Loop * **Core Mechanic (The "Weakness" Start):** The player starts with **almost zero stats**. * **Time Limit:** The player initially has only 3 seconds of playtime per run. * **Movement:** Extremely slow walking speed. * **Jump:** Almost no jump height. * **The Loop:** 1. **Run:** Player attempts to move right, collecting coins scattered in the air. 2. **Die/Reset:** When the "Time Limit" hits 0 or health hits 0, the run ends immediately. 3. **Shop:** A UI overlay appears allowing the player to spend collected coins to upgrade: *Speed, Jump Height, Time Limit, Armor, Gun Power.* 4. **Repeat:** Player goes further each time due to upgrades. * **Goal:** Reach the end of the level to defeat the Boss Robot. ### 4. Mobile Controls & Interaction * **Screen Orientation:** Landscape (Force landscape mode logic in CSS/JS). * **Touch Controls:** * **Left Thumb:** A floating Virtual Joystick or large D-Pad area for movement (Left/Right). * **Right Thumb:** Two distinct circular buttons: "JUMP" (Lower right) and "ACTION/SHOOT" (Upper right). * **UI Layout:** * **HUD:** Top-left for Time Remaining (Large text), Top-right for Coin Count. * **Shop UI:** Must be touch-friendly. Upgrade buttons should be large cards (minimum 60x60px touch target) clearly showing "Cost" and "Current Level". * **Feedback:** * Trigger `navigator.vibrate(50)` when collecting a coin. * Screen shake effect (camera jitter) when taking damage or hitting the ground hard. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Johnny Upgrade is an innovative action-adventure game that turns traditional gaming mechanics on their head. Instead of starting with basic abilities, you begin with literally nothing - no movement, no jumping, not even the ability to survive for more than a few seconds. This creative approach creates a compelling progression system that keeps players engaged as they gradually unlock fundamental gaming abilities.

Rated 3.2 out of 5 stars, this game offers a fresh take on the action genre by making every ability feel earned and meaningful. The concept is simple yet addictive: each attempt gets you a little further and a little richer, allowing you to purchase the skills needed to progress deeper into the adventure.

Core Features

Revolutionary Progression System

Unlike traditional games where you start with basic movement, Johnny Upgrade requires you to literally purchase the ability to run, jump, and survive. This creates an incredibly satisfying sense of progression where every upgrade feels significant and impactful.

Incremental Adventure Gameplay

Each playthrough builds upon the previous attempt. You'll venture slightly farther each time, collect more coins, and gradually unlock new abilities that expand your exploration possibilities. The game perfectly balances challenge with progress, ensuring you always feel like you're moving forward.

Unique Character Development

Watch Johnny transform from a helpless character who can barely survive a few seconds into a capable adventurer with superhero potential. The character progression is both visual and mechanical, making each upgrade feel meaningful.

Accessible Yet Challenging

While the game is suitable for all ages, it provides a satisfying challenge that requires strategic thinking about which upgrades to purchase first. The difficulty curve is perfectly balanced to keep players engaged without becoming frustrating.

Gameplay Mechanics

The core gameplay loop revolves around venture-die-upgrade-repeat cycles. You start each attempt with whatever abilities you've previously unlocked, explore as far as possible while collecting coins, then return to the upgrade shop to purchase new skills or improve existing ones.

Upgrades range from basic survival skills like increased health duration to advanced abilities like running speed and jumping height. The game cleverly makes you appreciate abilities that are typically taken for granted in other games.

Operation Guide

Controls are intentionally simple to focus attention on the progression system:

  • Arrow Keys or WASD : Movement (once unlocked)
  • Spacebar : Jump (once unlocked)
  • Enter : Interact with upgrade shop

The game provides clear in-game instructions for each newly unlocked ability, ensuring players understand how to use their hard-earned skills effectively.

Why Play Johnny Upgrade

This game appeals to players who enjoy incremental progression and unique gameplay mechanics. It's perfect for those who want a break from traditional action games and appreciate innovative design that challenges conventional gaming assumptions.

The satisfaction of earning basic abilities creates a deeper appreciation for character progression, making every upgrade feel like a genuine achievement. The game's creative approach to difficulty and progression makes it both accessible to casual players and engaging for those who enjoy optimization challenges.

Whether you're looking for a quick gaming session or a longer progression journey toward superhero status, Johnny Upgrade offers a unique experience that stands out in the crowded action game market.
