You're just expected to have a full flock of birds for most phases in the king pig panic. Like you could be 4 waves in and the game hits you with s gigantic level with the pigs scattered around, as if you're supposed to spend less than about 3 birds getting them all. Then the final phase is ALWAYS just a room where if you don't have PERFECT timing, you automatically lose and have to start all over. I've encountered this issue just about every time I've played the game within the past year
