Optimise scene when making an "Angry Bird" like game

Hi guys,

I have a question regarding what would be the best usage of hardware resources on an android platform.

I'm making a Angry bird like game that has chapters I thru V, and in it separate levels (up to 30). Now, when designing, should I create one huge scene where all the levels would be, and script would just position the camera based on what level it is, or should i create a scene for each level?

I don't mind the loading times, just what would be the best resource optimized way of not losing framerate.

Any advice is much appreciated. :)
