How do I make a Easter Egg for my game

Hi, I just want a Easter Egg for my game to make my game much better and simple. Thanks for the answers!!!

What do you mean by "easter egg" ? Usually, this word is used for a reference to another game or creation, reference placed somewhere in your own game. So, I don't really understand why it should make your project better and simpler.

You should take a loot at this : https://en.wikipedia.org/wiki/Easter_egg_%28media%29

As LeuNoeleeste said above, Easter eggs don't usually affect gameplay. An Easter egg usually refers to a message or feature that is hidden in the game.

I think what you want are cheat codes. Those do affect gameplay. If so, then you would need to be more specific as to what parts of your game that you want "better and simple".
