Level select game map question

Hi,

Anyone know how to add game level select map on BB 2

(like angry birds) How can you make a button green after you played it and how to lock other levels and only unlock when you are so far? Is that possible with BB 2? Anyone know this?

 

As far as I can tell, you can have different levels and a level select screen, but you can't lock down or limit access to levels, yet…

 

Ok thanks, I hope they add this feature soon!
