Is one C# enough to develop an Android game?

Question

Android

I want to implement several concepts of the games I invented. So far I plan only for Android on the Unity engine. 2D games with a story, enough text, resources, inventory, cut-scenes during the game, etc. As far as I understand, the basis for everything that is done in Unity is C #. So, will this language alone be enough for me to implement this kind of mechanic? It would be nice if you could help me figure out where to get the information from. Recommend any books, courses, etc.

Answer 1

No, either kotlin or java

Answer 2

limited enough
