Gameplay Tutorial Inside Your Game?

When the user interacts with your game for the first time, they need to know how to play it, right. What's the best way to add this Gameplay Tutorial inside the game for a newbies who just downloaded your game?

.... and I am not talking about just adding Text Label on GamePlay UI, I am talking about creating polished "HOW TO PLAY" tutorials to help users understand your game better, even if that entails a Demo Game Tutorial Scene as a separate world inside your game....

Any thoughts / videos / implementation guides?

Thanks!

 

BUMP!

No one creates "how to play " tutorials inside their games?

 

There are many games with a "how to play" menu, I like the way @Christoph did in his game "Void Jumping"

Void Jumping

 

@jcalle Great example, is that being made with Buildbox?
