What's the attraction of the dancing line? Advantages and disadvantages?

I just downloaded the dance thread today. The introduction says it is suitable for children over 5 years old. I really liked it after I played it. Talk about its advantages and disadvantages.

Disadvantages first: 1, too many advertisements. Probably because the game itself doesn't need money to buy. Therefore, almost every failure will lead to advertising time.

2. There is no step-by-step difficulty. Beginners are more laborious and abusive at the first level. Cancel the advertisement and ask 30 yuan. It's a little hard to accept.

Then there is the advantage: 1. The color matching and painting style of the game are very beautiful. It can be said that it is colorful and creative. Meet the requirements of teenagers for game quality. Patterns are similar to geometric figures. The quality of HD is pleasing to the eye.

2. Music. This is undoubtedly the biggest highlight of this game. Combining the principle of finger piano game and snake, it is not complicated to operate. But more than 90% of the original songs. There is even a BGM collection of this game in the music software. It can be seen that players like it very much.

3. Good theme. The game mode is rich. There are Chinese style, landscape architecture, land, desert and other modes. Every theme is appropriate. Use light and shadow. In a word, people like it very much. Have your own style.
