🎮 Browser Games Plus — Ultimate Game Template

Build your own side-scrolling runner right here on itch.  Pick a theme, drop in your characters & backgrounds, tweak difficulty, and export a polished game ZIP you can upload anywhere. When you’re done, take your creation to your audience—yes, even list it here on itch!!.

✨ What you can do

• Name your game and see it styled live in the HUD and loading screen.
• Switch themes (Neon, Forest, Sunset, Midnight, Candy) to recolor the screen, HUD, buttons, and text.
• Choose characters & backgrounds from the default pack or upload your own asset bundle.
• Enable obstacles & droppers (falling hazards) from the manifest—just check the ones you want.
• Tune gameplay: speed multiplier, spawn rate, lives, and optional double-jump.
• Export a clean game ZIP (no builder UI) ready for resale, publishing, and sharing.

🕹️ How to play (during preview & in exported game)

• Left mouse button → move left
• Right mouse button → move right (tip: on trackpads use two-finger click)
• Spacebar → jump (tap twice for double-jump if enabled)
• Use the on-screen controls (Start, Pause, Restart) and watch the live scoreboard.

🧱 How the Builder works

1. Pick Theme & Title: Choose a theme and type your game’s name (shows in HUD & the loading screen).
2. Characters & Backgrounds: Select from defaults or upload your own assets (see “Bring your own assets” below).
3. Obstacles: Check which regular obstacles and dropping obstacles you want from the manifest.
4. Gameplay Tuning: Set speed multiplier, spawn rate, lives, and double-jump preference.
5. Capture → Generate: Click Capture Game Info, then Generate Game File to download your game ZIP.
6. Upload & Launch: Create a new itch.io project, upload the ZIP, and you’re live!

Privacy note: Any assets you upload are mounted locally in your browser just for building your game and are cleared after export or refresh.

📦 What’s inside the exported ZIP

• index.html — your game page with compact control panel (toggle button in the corner)
• style.css — theme-colored UI
• game.js — the game logic (no builder UI)
• game-assets/manifest.json — trimmed to exactly the characters/backgrounds/obstacles you picked
• All referenced sprite sheets/atlases and background layers used by your build

📥 Bring your own assets (optional)

Want your studio’s art? Export a folder or ZIP named game-assets that includes your manifest.json plus any sprite sheets (.png), atlases (.json), and background layers (.png). In the builder, choose Upload assets and point to your ZIP File. The builder will validate and load everything on the fly.

{
 "characters": [{"id":"hero","sheet":"game-assets/sprites/characters/hero.png","atlas":"game-assets/sprites/characters/hero.json","scale":1,"facing":"right"}],
 "backgrounds": [{"id":"city","layers":["game-assets/backgrounds/layer0.png","game-assets/backgrounds/layer1.png"],"speed":[0.05,0.2],"groundRatio":0.78}],
 "obstacles": [{"id":"mushroom_red","sheet":"game-assets/sprites/obstacles/mushroom_red.png","atlas":"game-assets/sprites/obstacles/mushroom_red.json"}],
 "dropping_obstacles":[{"id":"falling_crate","sheet":".../falling_crate.png","atlas":".../falling_crate.json","behavior":"drop","trigger":"playerUnderneath","dropSpeed":12,"respawn":true}]
}

🚀 Promote your game (TikTok ready)

After export, your game loads instantly in the browser and shows a slick loading screen with your game title. Record short, punchy gameplay clips (screen capture or camera) and comment on this listing—fast runs, close calls, and stylish themes pop on vertical video. 

🛠️ Troubleshooting

• No sound? Click once on the game canvas to unlock audio (browser policy), and disable Mute in the controls.
• Right-click blocked? Some browser extensions intercept the context menu. Temporarily disable them for best results.
• Assets not showing? Ensure paths in manifest.json match your files inside game-assets/.
