# Use Cases

## 1. Jump Rope Game

**Key features**:

- **Endless runner mini-game**: Dodge obstacles, catch birds, manage lives and brief invincibility, score points, and handle increasing difficulty. Supports touch taps or keyboard Space / Up Arrow controls.
- **Jump rope hardware interaction**: Before starting the game, users can discover a jump rope device and set it to "free training" mode. At the start and end of a game, DP commands are sent to start or pause counting. Real-time jump counts are subscribed to and converted into in-game jump input, enabling "real rope jump -> game character jump".
- **Dual-entry gameplay**: The home page offers "play with device" and local touch-only play. When connecting a device, a top banner shows connecting, success, or failure states and supports reconnection. If users enter in portrait mode, the page tries to switch to landscape to fit the game layout.
