Well, I finally did it!!! I made it past leverl 352 with 3 stars. In the end I had 1 move left and 7 butterfly's on the board and I needed 8 to complete the level. So I used x2 star gems next to each other to clear 6 of the butterfly's and I used 50 coins to add 5 more moves, I wasn't going to lose this level again. I have finally done it.
My tip is to just play until you have 3 moves left and count the remaining butterfly's. If you have enough to finish the game, use special gems to help. It is doable.

Update. I got down to 5 butterfly's with 3 moves left and the game crashed. It really doesn't want me to pass this level. Ugh!

I have been stuck on this level for weeks as well. Thought I was the only one. Wrote a review on the app download page stating I have been stuck for weeks. This Basically means I have to give up the game until it is either fixed or someone has a massive hint. There just aren't enough butterfly's coming up in that level and there are 2 times there are no butterfly's. It is impassable. The lowest. Can get is 10 butterfly's left.
