Can I Rotate The Stage?

[qiangzi]

Hey guys, I want to make a game which has two layers like the uploaded images.

It is a skiing game, there are background elements in the layer1.

Also there are game elements in the layer2.

I don't know how to create layer in the game.

So I think that I can use the phaser.world as the layer1 and the phaser.stage as the layer2.

However, I found that I could not rotate the whole stage such as 

game.stage.rotation=0.1;

It doesn't work.

So I want to know how can I rotate the stage?

Or can you give me some idea for this game?

Thanks.
