King of fighters Dream Battle! Why do so many people say it's simple? . . ?

Take a closer look at their comments, "I thought the game was too simple, a piece of cake! Just go through customs! " I don't know what the concept of fighting game clearance is, and many comments are such a sentence, which is obviously a casual remark or copied from it. Take a look at the initial comments of the game 4399, and some people call it difficult. It seems that the initial comments also mentioned some methods of infinite connection, so you can take a look at them and maybe it will be easier. Don't pay too much attention to what others say. Some people's comments are nonsense. Maybe the people who call this game casually have never played or played expert-level difficulty.
