If you just want to run the game on Desktop (Windows/Linux/macOS), without downloading the source-code and compiling it yourself, check out the Releases tab. To run the game on Android, install it from Google Play.

Windows: gradlew desktop:run
Linux/macOS: ./gradlew desktop:run

More often than not, running the game from the command-line won't work. I suggest installing Android Studio and opening the project there. Wait for Gradle to download all dependencies, then run either the android or Desktop configuration.

If you want to run the game only on Desktop (excluding Android), you can use IntelliJ IDEA.

The configurations previously mentioned, android and Desktop, won't show up in Eclipse.
