Congratulations !!, really good to be your first project on Godot.
I love the sounds ;)
Tip: Try next time to add a better "Game Feel". For example, when the King attack a Pig, throw the pig to the air to show that the attack is powerful and make some screen shake a little bit. The same thing when the bomb hits you. This type of things are easy to implement and makes the game more fun to play :D
Good Job !!
