After 10 Scenes, Speed Up Gameplay?

Hello

How can I set my game up, so the game is moving at the default speed for say 10 scenes, then get slightly faster for the next 10, then say even faster for the remaining of the game?

I feel like my game needs to get more difficult as the user progresses

Thank you

 

It's possible to use actions of type gameplay to change time warp value of world.
put an invisible action in the start of each scene after 10 scenes

 

That way, I'd have to play my scenes in ordered, wouldn't I?
I'm still hoping to randomise them.

 

So you should arrange them like this on your timeline I suppose
