Is the name easter egg already a thing? If it is I'm gonna start smashing my keyboard and hoping to get it right.
Also, are you currently working on the gameplay mechanics, story, items, or the intro scene? Oh wait...
Suggestion! What if you make the game intro not like a cut scene that you can only watch but also as a playable scene? If you do a certain thing in the intro you'll unlock or get something when you start the game. Maybe a starter supplies, some clothes, weapon, or perhaps even a hidden skills that you can only unlock in the intro? Now THAT is cool.
