First of all, this is the ultimate music library. I don’t think I can’t afford it, but can you give me one or two opportunities to experience the music (I really want to play it again and add fireworks). After all, it’s fun and I’m willing to pay for it. Secondly, there is this new daily challenge. I wonder if the score can also be divided into four, five and six keys to play. It doesn’t matter if the four-key reward is smaller. Six-key is really unfriendly to me, a thumb player. And about the new song lab, I actually have favorite songs that I want to change, but this time only four songs appeared and none of them are what I want. I want to ask if other songs will be exchanged in the future. What an opportunity. I really like this game, and I really hope it can get better and better. Here is the final screenshot of a newbie who is seriously playing it.
