The walkthrough will not help due to the fact it's a different version than this one. The way a group is released isn't the same pattern so on certain levels (*cough* hatsworth *cough*) where it has two bombs in a group on the bottom and one on top, you can't pull off that same shot making the walkthrough useless. If you don't believe it's a different version, if you look it says 2 shots for gold on hatsworth, which is not the case anymore.
