To reproduce this bug, set the music sync to -1.00. Since music sync feature actually just delays the line movement if set to negative, when you get to the part of the music that the line flies, it flies earlier.
#Line flies earlier in The Storm Blues Remix when music sync in -1.00

Alright! Thank you! Also, sorry for making that post that wasn’t an actual bug. Now I remember that sometimes you need certain points to be able to pay real money to unlock a level and, as a player that already claimed that task, as well as that I completed all levels, I thought it was meant to be to unlock the option of unlocking with gems, since the in-app purchase already appeared in the UI when I opened the game.
