Another difference that I haven't seen anyone talk about yet is the fact that while in both games, as you progress, you get different types of ammo, in CTC, you can switch between the different types of ammo at will, while in angry birds, you're stuck with the ammo types you're given, in the order they're given.

While this reduces complexity in Angry Birds, it also means you can't always choose the most devastating ammo, which adds a bit to the challenge.
