Hello,
I can make your game for you in Unity 3D for Android. I have previous experience in developing games and have made several in Unity, and even published a collection of games in the Google Play Store. In the past, I have made several 2D and 3D games in Unity, such as 3D chess, memory game, hangman, and much more. My Master's dissertation was about an AR app I made myself in Unity
I have a few doubts about the the game you want, namely where and how you want to use AR. I'm looking forward to working with you!
Best Regards,
Inês C.
