This may pose the risk that the public could easily discover game codes. Since August 1, 2019, Google has required all games to support 64-bit architecture, the Unity developers needed to enable the Scripting Backend: IL2CPP feature when building and publishing games to the Google Play Store.

In this tutorial, you will know how easy it is to reverse engineer a Unity-based game on Andoird. 3D Tanks Game Tutorial that uses simple game mechanics, integrating world and screen space UI, as well as game architecture and audio mixing.

However, after doing some experiments, I realized my theory is wrong and decided to write this tutorial.
