A little catalogue of self-contained browser games. Each game is its own folder of static HTML/Canvas + vanilla JS — no build step, no dependencies, no external assets — and gets a tile on the home page plus a top-left ‹ Menu / Komyo Games › nav. Every game follows the same flow: menu (pick a mode) → play → scoreboard (with share buttons). The home page groups tiles into Single player and Multiplayer sections.
| Game | Folder | About |
|---|---|---|
| Asteroids | games/asteroids/ |
Fly/shoot/survive — classic arcade + roguelite modes, speedruns, mobile controls |
| Keep Defender | games/tower-defense/ |
Fixed-path tower defense — towers, gold, mage/fast-forward/boss telegraph (Castle & Parchment theme) |
| Stack | games/stacker/ |
One-tap tower stacker — slice the overhang, chain perfect drops (pastel-clean theme) |
| Neon Snake | games/snake/ |
Grid snake in glowing neon — arrows/WASD/swipe, deadly walls |
| Meadow Flyer | games/flappy/ |
One-tap flyer through a soft storybook meadow |

The arcade is a Progressive Web App — install it to play fullscreen & offline, no app store:
- Android (Chrome): tap the 📱 Install button on the home page, or menu ⋮ → “Add to Home screen”.
- iPhone (Safari): Share → “Add to Home Screen”.
- Desktop (Chrome/Edge): the Install button, or the install icon in the address bar.
Install individual games too. Every game is its own Progressive Web App — open a game and use Install / Add to Home Screen to put just that game on your home screen (its own icon, opens fullscreen, plays offline). Handy if you only want one.
- Create
games/<slug>/index.html— load the shared kit in<head>(game-kit.css+game-kit.js) and usegamekit.nav(),gamekit.sound,gamekit.shareRow(),gamekit.pwa()for the nav / sound + mute / share / PWA. Keep game logic inline with awindow.__testhook and the menu → play → scoreboard(+share) flow. - Add one entry to
games.js:slug,title,blurb,icon,accent,tag, and optionallysoon: true(greyed coming-soon tile),mp: true+players(e.g."2–4P", Multiplayer section),badges: ["new"]/["pick"](gold/purple tile badge). - Add
games/<slug>/test.mjs(dependency-free headless harness; preload../../game-kit.jsin the sandbox before the inline script) and keep it green. sw.jsSHELLincludes the HTML, icons, and../../game-kit.js+../../game-kit.css(offline).
node test.mjs # catalogue wiring + Keep Defender logic + boots every live game
node games/<slug>/test.mjs # any single game's own suite (e.g. games/snake/test.mjs)
node games/asteroids/test.mjs # the asteroids launcher's suiteDependency-free headless harnesses (mock the DOM/canvas, drive each game via a
window.__test hook). Keep them green.
