Level 10565 issues

Looking at the video posted above here, I can see that if you destroy any of the keys then you might fail this level. To unlock the dragon or cherry on the right you need 6 chocolate, but the chocolate is caged in on the left row and can ONLY spread into the keys. If you for example play a colour bomb to remove the keys too soon then this would be unachievable. I suggest you don't play any starting boosters on this level. This level has a set sequence of events which needs to be followed.
