Focus Playground — VS Code mini‑games for healthy waiting

Why? Modern AI dev flows mean lots of “run → think → wait”. Instead of doom‑scrolling, take a 30–60s brain break inside VS Code.

What it is

A lightweight extension that opens a polished webview with micro‑games designed for short, satisfying sessions:

• Aim Dots — click targets before they fade (reaction & motor control)
• Sequence Memory — repeat an expanding 3×3 pattern (working memory)

High scores are saved locally. Default session length is 30s (configurable).

Install (local dev)

# in the folder where you unzipped this project
npm install
npm run compile
# then open the folder in VS Code and press F5 to run the extension

Or package & install:

npm run package          # produces focus-playground-*.vsix
# then in VS Code: Extensions → ... → Install from VSIX...

Use

• Command Palette → Focus Playground: Open
• Default hotkey: Ctrl/Cmd+Alt+F
• Status bar → ▶ Focus Playground

Idle nudge (optional)

By default, after ~25s of inactivity the extension shows a friendly “Play” prompt. Configure under Settings → Focus Playground:

• focusPlayground.autoShowOnIdle (true/false)
• focusPlayground.idleSeconds (5–180)
• focusPlayground.defaultDuration (10–180)
• focusPlayground.sidebar (open beside editor)

Privacy

No telemetry. No network calls. Everything runs inside VS Code’s sandboxed webview.

Roadmap ideas (PRs welcome)

• “Type Burst” micro typing test
• Breathing/box‑breathing card for quick resets
• Tiny chess tactics & code golf mini‑puzzles
• Audio cues & haptics (where supported)
