InfiniteTunnel is a little android game I made during my freetime using Unity3D
Install Unity3D import the repository as a project and compile it.
Or just use the .apk in the APK folder and use it on the android phone of your choice.
Or download it from the Google Play Store
Just tilt your phone to control the spaceship.
You can use all of the files as you want. There should be some bugs.
