The basic plot of Angry Birds is simple: a group of angry birds are engaged in a fierce battle with a group of greedy pigs. Players need to help the birds use the slingshot to launch themselves into the pigs' camp and destroy their buildings and defenses to save the eggs that the pigs have stolen. The game uses a physics simulation of the gameplay, players need to control the firing Angle and force, in the best way to destroy the pig's line of defense.

One of the biggest highlights of Angry Birds is its simple yet challenging gameplay. The game is very easy to get started, you only need to simply pull the slingshot to launch the bird. However, as the levels progressed, the game gradually introduced more complex elements, such as different types of birds with different special abilities, and different shapes and materials of buildings requiring different attack strategies. This allows the game to remain simple and easy to understand but also has a certain depth and challenge, which attracts players to explore and try new solutions.

Angry Birds is also known for its cute and unique character designs. Each bird has its characteristics and personality, such as the red bird is the basic attack unit, the yellow bird can accelerate, the blackbird can explode, and so on.

In addition, the background music and sound effects of the game are also very pleasant, adding a lively and pleasant atmosphere to the game.

There are some downsides to Angry Birds, however. First, the game's advertising and in-app purchase system may be disruptive to some players. The presence of ads can sometimes interrupt the game experience, and in-app purchase systems can cause some players to feel limited in their progress. While these ads and in-app purchases don't seriously affect the overall quality of the game, they are still a blemish for some players.

What is more, the innovation and novelty of Angry Birds have waned over time. Although Rovio Entertainment has released many spin-offs and sequels, such as Angry Birds Seasons, Angry Birds Rio, etc., these games do not have much innovation and breakthrough in the core gameplay, which may leave some old players tired and lack of freshness. Those who have already played the Angry Birds series, may be hungry for more innovation and change to keep interest in the game.
