I can really relate to those problems! I actually spent 2.2m on an expansion while chaining!

In terms of minimising "crystal risk", try to position the village before you begin so that the right hand side is relatively clear of stores/resources. That way, you won''t inadvertantely click on a store and spend crystals. Also, try going from right to left while chaining. You'll never lose another crystal again. Finally, be "light-handed" when chaining - I've found that I make more errors when I "pound the screen" instead of just whisking across it.

Good luck!
