I passed level 10965 by using the free fish-booster at the beginning. The fish took the first key and at the end I used the 6 extra free moves. Finallly past level 10966 with +35 moves (10 gold)
Level 10963 needed two times +35 moves, so +70 extra moves, ridiculous!!! Now stuck on level 10966, waiting to reach +35 moves. Boring, boring, boring….
