# Handheld console

> Gizmo pack gadget: a pocket game console with a big rounded corner, a d-pad, A and B buttons, start and select, speaker slots and a screen that plays a tiny pixel runner: a block hero hops obstacles over scrolling hills, and the A button presses on every jump. A tap makes the hero leap for a coin and the screen flash. Raymarched in WebGL, six palettes.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/gizmo-handheld/gizmo-handheld.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/gizmo-handheld
```
