FLAPPENING

Worlds

Eight worlds are parodies of places the internet lives in. Each one has its own palette, obstacles, coins, ground UI, ambient effects, music and death screen.

World	Obstacles	Coins	Details	Death
Claude Code	tool-call panels (Edit, Bash, Read, Grep, Task) with live diffs	orange tokens	a scrolling session, Flapping... spinner, prompt box	INTERRUPTED
ChatGPT	reply towers with code blocks and typing dots, model pills (GPT, 4o, o3, AGI)	white tokens	a chat that scrolls behind you, the composer types flap flap flap, the famous disclaimer	HALLUCINATED
Grok	black monoliths with a slash, THINK / SEARCH / FUN MODE chips	ring-and-slash discs	starfield, an event horizon with orbiting debris, shooting stars, "Grok is 88% sure this bird survives"	SPAGHETTIFIED (the screen stretches into the bird)
X / Twitter	towers of posts with POST / LIKE / RT pills	blue checks	a live timeline, your flyer as the avatar, trending #FLAPPENING, hearts in the air, notification badge = score	RATIOED
GitHub	branch towers of commits with diffstats, MERGE on top, OPEN below	stars	a scrolling contribution graph, repo tabs, checks, a star counter that is your score	MERGE CONFLICT (with conflict markers)
Binance	an order book: red asks with SELL above, green bids with BUY below, you fly the spread	gold coins	candles, a live price line, ticker tape, PNL and a margin bar that fills up	LIQUIDATED
pump.fun	stacks of giant pills	mini pills	token cards, a pump-and-dump curve, a bonding-curve bar you fill by scoring, live trades tape	DEV SOLD
TikTok	neon video towers with a cyan/red split, + caps	hearts	pulsing logo, equalizer, the action rail with your flyer, likes that grow with your score	FLOPPED (RGB glitch)

The brand worlds are fan parodies. FLAPPENING is not affiliated with or endorsed by any of these companies, and every mark is drawn in code.

Flyers

Every flyer is hand-built pixel art with cel shading, a 6-frame flap, blinking eyes, its own flap sound, its own particles and its own perk.

Classic worlds

World	Obstacles	Ambient	Death
Cloud Nine	marble columns with ivy	sun rays, bird flocks, petals	stars spin around your head — OUCH!
Wasted City	neon towers with glowing signs	synthwave sun, rain, searchlights, a police chopper at 4 stars	world turns grey — WASTED
To The Moon	green PUMP / red RUG candles that move	twinkling stars, rockets, a live chart	red chart crashes across the screen — RUGGED

Pipe styles

Pick the obstacles in PIPES — they work on every world:

World Default (marble, tool calls, neon towers, candles) · Sausage Stack (grilled links + bun) · Rocket Silo (nose cones pointing at you) · Candy Canes · Desert Cactus · Giant Pencils · $FLAP Stacks (gold coin towers) · Chaos Mix (every pipe is a surprise)

Game feel

• squash & stretch on every flap, per-flyer trails (flames, jets, mustard, crumbs, hearts, feathers, bombs)
• PERFECT passes through the centre, CLOSE! near-misses in slow motion
• every 10 points: giant banner, confetti and a fanfare
• COMBO: chain PERFECT / CLOSE passes — 3 in a row (or every 25 points) starts FEVER: rainbow trail, rainbow screen edges, afterimages, coins x2
• lightning storms over Wasted City
• hit-stop, screen shake and flash on death, coins fly into your counter
• glow on coins, neon and power-ups, speed lines when the world speeds up, pixel iris transitions
• shield and magnet power-ups, moving gaps as you improve

Everything else

• flyer and world carousels with live animated previews, stats, swipe support and a quick-jump icon strip
• main menu world tour: the background walks through all 11 worlds with a crossfade while your flyer threads the pipes
• animated logo, coin shop, a score-locked secret flyer, GitHub and X links in the menu
• leaderboard: top 10 per world on every device + optional world board (worker/)
• medals: bronze 10, silver 20, gold 40, diamond 80 — with a count-up and confetti on a new best
• Share on X from the game-over screen, chiptune music and SFX generated live, mute button
• PC: Space / ↑ / click, ← → in menus, P to pause · phone: tap, swipe, full-screen portrait, installable
• zero dependencies, zero build step: plain HTML + canvas + JS
