I am really frustrated with level 1351!! I went through an entire game with only one key dropping.

I've wasted way too much time and money on this level!  And lost way too many lives given to me by friends.  I am not liking this game right now. Never have I been so frustrated with a level.  The keys don't drop ... can't pass the level if the keys don't drop!

I really hope that this helps...

The keys drop of course, but you just have to make strategic moves as with most levels.
