Unity how to save?

Question

Unity

I want to make a save for my clicker game. The bonus should be saved in the save, the improvement panels (let's say I bought it and the panel disappeared and so that when you restart the game it does not appear and is also missing) and money.
How to implement it?

Answer 1

Read the documentation for PlayerPrefs

Answer 2

PlayerPrefs, ScriptableObjects, save on some server
