Add A Timer ?

Is there any way I can add a timer to a specific world?

Any help appreciated.
Thanks

Thanks @trudnai @Nihat ..But there is one problem. I have also in that world points which player has to earn. Not coins but points, so now when timer in going, so is the points of the player, which I don't want it to be. Player has to earn the points.

 

You can attach a menu jump to an object and have that object move in from the left or right (or from the top or bottom). You could also look into adding an enemy to the player animation that slowly moves closer to the player at a certain speed relative to the time you want.
