A retro up-to-8-player sideways-scrolling one-button-each Android action shooty game.
Development should work nicely with Android Studio (log an issue if not).
If you prefer the command line, install the Android SDK v25+, make sure adb is in your path, and connect your device or start an emulator, and use the following commands.
./gradlew installDebug
adb shell am start -n "net.artificialworlds.tunnelwar/net.artificialworlds.tunnelwar.TitleActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER./gradlew test./gradlew connectedAndroidTest
