I could never get into Angry Birds but yeah, level design is a big part of ANY game. Portal is amazing in part because they tested the HELL out of it and put a LOT of effort into teaching you how to play the game - the tutorial doesn't end until you leave the fire pit, IMHO.
AB also ads a lot of things to the basic "you have a slingshot, knock stuff down" - there's different birds that act differently, different things to hit, etc. Start with one system that's fun to play with for a little while, add complications when it starts to get boring. Right now these folks have, I dunno, the first ten minutes of gameplay.
