Where to start with making a mobile game?

Question

So as the title suggests, I would like to know where to start when it comes to making a mobile game.

I want to create something simple and 2D, like a simpler version of geometry dash or something along those lines, but I have no clue where to start.

I need to know what code to use, how animations work, if I should use unity, unreal, or any of the other gaming engines out there and how to make it compatible for any and all mobile devices, etc.

If anyone can give me any tips or pointers that would be great, I just need to know where to start for practice, TY

You can use unity. But you can use many different engines aswell.

I did use corona for my own game. You can look at it here:
