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
