I’ve made an Android-like game this week with Unity and I’ve pushed to my github, then feel free to download the source code. If you prefer to copy the link, it’s here: https://github.com/joaokucera/unity-asteroids.
There is a live demo here to play.
There is no licence, no condition, download and use it as you want. I hope this help you to study #unity3d and if this help you then give me a github’s star.
