Mineflappy

Minecraft Flappy Bird — a single-file HTML5 canvas game. No build step, no dependencies, no assets. Everything (sprites, font, music, sound) is generated in code.

open index.html          # that's it - it runs straight from the filesystem

Deploy to Coolify

Option A - Dockerfile (recommended)

The repo ships a Dockerfile that serves the game with nginx.

1. In Coolify: New Resource → Application → Public/Private Repository
2. Repository URL: http://forgejo-b82b4lpyyzyg40thdsjdd38i.163.245.214.68.sslip.io/David/MINEFLAPPY-GAME.git
   • Branch: main
   • Build Pack: Dockerfile
3. Dockerfile Location: /Dockerfile (default is fine)
4. Port: 80 — set this under Networking → Ports exposes
5. Health Check Path: /healthz
6. Hit Deploy.
7. Add a domain: Settings → Domains → Add Domain - e.g. game.yourdomain.com
   • Tick Force HTTPS and let Coolify/Traefik issue the Let's Encrypt cert.
   • Coolify routes the domain to the container's port 80 automatically.

Push a new commit and Coolify rebuilds and redeploys it.

If you get "502 Bad Gateway": the container is healthy, but the proxy can't reach it. The usual cause is an empty Ports exposes field — when it's blank Coolify routes to port 3000 instead of 80. Put 80 in that field and redeploy. The bundled nginx.conf listens on both 80 and 3000, so the game is served either way, but setting the port correctly is still the right fix.

Option B - Static Site (no Dockerfile)

If you'd rather not run a container:

1. New Resource → Static Site with the same repo
2. Build Command: echo "static" (there is nothing to build)
3. Root Directory: /
4. Deploy, then attach a domain as above.

Option C - docker compose

A docker-compose.yml is included if you deploy by compose instead:

docker compose up -d --build
# game is on http://localhost:8080

---

Run it locally with Docker

docker build -t mineflappy .
docker run --rm -p 8080:80 mineflappy
# open http://localhost:8080

Layout

File	What it is
index.html	The entire game - markup, CSS and JS in one file
Dockerfile	nginx:alpine image that serves index.html
nginx.conf	Server config: no-cache on the game, gzip, /healthz
docker-compose.yml	Optional compose deployment

The game

Six birds, each with one ability:

Bird	Ability	Effect
Chicken	Double Flap	Every 4th flap is 34% stronger
Enderman	Teleport	Blink 70px forward (refused if a pipe is in the way)
Allay	Allay Magnet	Nearby gems fly to you
Blaze	Melt	Burns away the next pipe, widening its gap
Phantom	Phase	Fly through anything for 1.2s
Wolf	Howl	Slows the whole game to 55% for 2s

Also in: five biomes that change with your score (Plains → Desert → Mineshaft → Nether → Ice Peaks), a day/night cycle, weather, gold/bubble/wings/lucky-cube pickups, difficulty settings, bird unlocks, per-bird best scores, a daily challenge with a shareable code, a ghost of your best run, and 2-player on one screen.

Controls - Space / W / ↑ / tap to flap, F to use your ability, P to pause, C on the game-over screen to change bird. In 2-player mode Space is player 1 and ↑ is player 2.

Progress is stored in localStorage under mineflappy_v2.
