How do I create multiple levels to be shown in the same page?

Yo, lads!

I wanna know how do I show multiple levels in one screen. For eg, in the game Drop Block, all levels would be shown in the same screen. I'm conceptualizing a game like that and I need help.

Cheers.

 

Drop Block has small scene so just small scene and it going to apear

 

Do you know how to create smaller scenes?

And do you know what preset I should use to achieve that?

Help!
