Hi @Rogo788 and welcome to our adorable Community 😊 The studio is always monitoring the players' experience with levels. If they are too hard or too easy according to these results, they might tweak it a bit. If you saw the videos with more moves, they were probably recorded as soon as the level was released.
However, I will post some tips from someone who is very good at it and the video with 12 moves too.
I hope this will help you. If not, I strongly recommend taking a break for a day or two to clear your mind. It helped me numerous times to finish the level once I come back to the game. Good luck and keep crushing 🍭
