In scratch, you actully have to make a new level....

Assuming you're making a game that has the background as the level and a goal you need to get to, the scripts should look something like this:
On Character
When green flag clicked Forever if <touching goal> broadcast next level wait until <not touching goal> End
On Stage
When I receive next level next background

I tried your suggestion Harakou. The on problem though is that if you're just switching costumes you cant change scripts for the second lvl. For example this is the script for one of my monsters.
<when green flag clicked>
<forever>
<hide>
<wait(2)secsc>
<show>
<wait(4)secsc>
I cant change the amount of secs that the monster is dissappearing to make it harder. If you do know how to thought then pls tell me.

You can use variables to adjust that. For example, you could change your script to look like this:
[blocks]<when green flag clicked>
<forever>
<hide>
<wait( (( <{ level }> <*> 2 )) )secs>
<show>
<wait( 4 )secs>
<end>[blocks]
