👑 Regimon GO

A Pokémon GO–style catching game that starts at Regis High School on 84th Street and covers all of Manhattan from 97th Street down to the Battery, the harbor islands, and Hoboken, Jersey City, Union City and Weehawken across the Hudson. Catch 103 original Regimon, from the humble Homeworm to the Celestial Metropolaris and Libertitan, then fight AI trainers in real-time battles.

▶ Play: https://vdeaton29-collab.github.io/regimon-go/ (installable, and works offline after the first visit)

Two ways to play

Mode	How it works
🎮 Explore	Tap or hold the map (or use WASD / arrow keys) to walk. Open the map to fast-travel anywhere. Works offline.
🛰️ Live GPS	Your real location moves you. Walk around Manhattan or Hudson County to find Regimon near you. Your browser will ask for location access.

Switch modes any time from the 👑 menu or the mode badge in the top-left corner. Pinch or scroll to zoom the map. Stay aware of your surroundings when playing in Live mode.

Safe & Experimental

You start in Safe mode, which covers the most polished areas: all of Manhattan below 97th Street, Roosevelt Island, the harbor islands, and Hoboken plus downtown Jersey City (you can cross the rivers between them). Turn on 🧪 Experimental mode in the 👑 menu to open the whole map — Brooklyn, Queens, Union City, Weehawken, Journal Square and the Heights — while those areas are still being finished.

Online, names and music

• Trainer name — pick one when you start (or in the 👑 menu). It shows above your player.
• 🌐 Online mode — opt in from the 👑 menu to see other trainers on the map in real time, with their names and levels, and tap them to wave 👋. The online button shows how many people are playing. Online shares your name, level and neighborhood through a public server; your map position is shared only in Explore mode, and your real location is never sent in Live GPS mode. (Online works on the GitHub Pages site.)
• 🎵 Music — twelve chiptune tracks with echo, arpeggios and drum fills: Upper East Side, Central Park, Midtown Nights, Across the Hudson, Harbor Shanty, Express Line (subway), Wild Encounter, Legendary Encounter, Trainer Battle, Gym Showdown, Online Duel and Champion Battle. On Auto, the soundtrack changes with the neighborhood. Pick a favorite in the 👑 menu.
• 💬 Chat & emotes — tap 💬 to pop emotes over your trainer; when online, chat with everyone (messages are filtered, rate-limited and can be muted per player).
• ✨ Teleport & ⚔️ Duels — tap another trainer to wave, teleport next to them (only to players in Explore mode), or duel: both trainers pick a team, each battles the other's real team, and whoever wins with more HP left takes the duel.
• 🔐 Accounts — create a username and password in the 👑 menu to back up your progress and load it on any device. The save is encrypted in the browser with a key made from your password (PBKDF2 + AES-GCM) and stored on three public MQTT brokers; the password never leaves your device and can't be reset.
• 🚇 Subway & ferry — tap a station to ride to any other station.
• ⬆️ Evolution — 312 Regimon: 50 new three-stage families plus evolved forms of the originals. Catches give family candy; evolve from the 🗃️ Caught screen.

The map

Real geography from OpenStreetMap across the whole map: every street (with its name), building footprint, park, pier and rail line, plus real shorelines. Parks are drawn in full detail: 28,000+ real trees, woods, lawns and meadows, flower gardens, playgrounds, running tracks, pools, fountains, statues, park paths and bike paths, and sports fields marked by sport (baseball diamonds, basketball and tennis courts, soccer fields), with names for spots like the Great Lawn, Sheep Meadow and the Ramble. The map streams in chunks as you walk, and the 👑 menu can save the whole map for offline play. Underneath is a simplified map (the tilted Manhattan street grid with every numbered street and avenue, Broadway, Central Park (the Reservoir, the Great Lawn, the Lake), the High Line, the bridges, and more than 100 landmarks. Every landmark is a stop. Each neighborhood has its own Regimon:

Area	Look for
🏙️ Midtown	Neonoir, Skyscraptor, Vesselith, Chronowl, and the Mythic Empyreon
📈 Financial District	Bullion, Bearish, Tickertaper, Oculuxe, and the Celestial Metropolaris
🗽 New York Harbor	Ellisprite, Tugotter, and the Celestial Libertitan
🌉 Hoboken, Jersey City & Union City	Cannolisk, Palisaur, Salsamander, Hamiltron, Pathfinder
🏮 Chinatown	The Legendary Lanternwyrm
🌊 The Hudson & East Rivers	Hudsonyx, Kraketeer, Riftdrake, Bridgoyle, Gatekeel, Mayorca
🚇 Subway & PATH stations	Subwayrm, Pizzarat, Voltergeist, Magmalith, and the Mythic Voidrail
📚 Regis & other schools	Owlgebra, Quizard, Scholardrake, Regisaurus, Solregis
🌳 Parks	Squirrelio, Highlinx, Umbrawolf, and the Mythic Solhenge

Rarities: Very Common → Common → Uncommon → Rare → Legendary → Mythic → Celestial. The rarest appear under a beam of light. About 1 in 64 Regimon is a ✨ shiny with different colors.

Battles

Real-time, like Pokémon GO's battle league: hold to fast-attack and build ⚡ energy, spend it on special attacks (time the meter for full power), and use your 2 🛡️ shields wisely. Elite Regimon have ★ signature abilities with their own effects and sounds. Beat all 15 arena leaders, from Ranger Rosa on the Great Lawn to the Harbor Guardian on Liberty Island, and climb the ranked Battle League from Freshman to Valedictorian.

Tech

Plain HTML, CSS and JavaScript with no build step and no dependencies. The map is drawn from hand-entered geography (shorelines, street grids, parks, landmarks) projected from latitude and longitude, so GPS positions line up with it. Every creature is SVG drawn in code, and all music and sound is synthesized with Web Audio. A service worker caches the game for offline play.

index.html            page and UI shell
style.css             styles
sw.js                 offline cache (service worker)
manifest.webmanifest  install as an app
js/osm.js             OpenStreetMap coastline, parks and stops (generated by tools/build-osm.js)
js/osm/c_*.json       OpenStreetMap map chunks, loaded as you walk
js/online.js          online mode (tiny MQTT client over WebSocket)
js/geo.js             geography: projection, shorelines, grids, parks, landmarks
js/data.js            creatures, rarities, arenas
js/art.js             procedural creature art (and shiny variants)
js/music.js           chiptune music, attack sounds and effects
js/battle.js          real-time battles: energy, shields, type chart, AI, particle effects
js/game.js            map rendering, GPS, spawning, catching, Regidex, Battle League

The map data is built from the BBBike New York extract of OpenStreetMap (put NewYork.osm.pbf in tools/cache/, then run node tools/build-osm.js; without it the script falls back to the Overpass API).

To run it locally, serve the folder with any static server, for example python -m http.server, then open http://localhost:8000.
