# Air Labyrinth
2+
3+
![Air Labyrinth](./.catalog/screenshots/1.png)
4+
5+
This is a simple game where you have to navigate a ball through a maze. The game is controlled by tilting the Flipper Zero with a Video Game Module attached. You can also play the game using the Flipper Zero's d-pad.
6+
7+
## How to play
8+
9+
1. Attach the video game module to the Flipper Zero.
10+
2. Open the Air Labyrinth game (`Apps`/`Games`/`Air Labyrinth`).
11+
3. Tilt the Flipper Zero to move the ball through the maze.
12+
13+
## Version history
14+
- 0.1.0 - Initial release by @CodeAllNight (https://youtube.com/@MrDerekJamison/about)
15+
16+
17+
## Other
18+
19+
This game was made based on the [air_arkanoid](https://github.com/flipperdevices/flipperzero-good-faps/tree/dev/air_arkanoid) and [flipperzero-game-engine-example](https://github.com/flipperdevices/flipperzero-game-engine-example) projects. Thanks to the authors of these projects for the inspiration and the code.

# Flipper Zero Game Engine
2+
3+
Welcome to the Flipper Zero game engine! This engine is designed to help you create games for the Flipper Zero device.
4+
5+
## Example App
6+
7+
To see the game engine in action, check out our [example app](https://github.com/flipperdevices/flipperzero-game-engine-example). This app demonstrates how to use the game engine to create a simple game.
8+
9+
## Contributing
10+
11+
We welcome contributions to the Flipper Zero game engine! If you have any bug reports, feature requests, or pull requests, please submit them to the [official repository](https://github.com/flipperdevices/flipperzero-game-engine).
12+
13+
Happy game development with Flipper Zero!
