The most important part of this game is putting together a team of birds that are capable of taking down the pigs who stole their eggs. Below are several ways that will help you build that team.
Keep Rebuilding
It is important that you are always have the most powerful birds possible in your lineup and the way to do this is to constantly rebuild your team by looking at your inventory everytime you unlock a new bird and exchanging old birds with more powerful ones.
Defeating Powerful Enemies
Whenever you encounter powerful enemies you may want to consider attacking them from behind by bouncing off of the battle boundaries or other birds before releasing them. Attacking an enemy from behind will also earn you a bonus.
Avoid Taking Damage
Always make a note of the number above a pigs head as this indicates the amount of time they need to wait before they can attack you. If you take advantage of this information by attacking them before they can attack you back you will maximise your combat effeciency and be able to complete missions and battles without taking much damage.
