Does anybody have some tips for what I assume is the last bit of Deliverance? You have to swing the 'rope' into the fire to burn away the bonds supporting the undelete package, but I can't seem to do this -- the goos barely make any impact upon the rope, and they quickly proceed to make their way to the corner of the 'support' and get stuck moving in a triangle.

This is by far the most frustrating segment (of what I feel is a very frustrating chapter) so far; tips would be appreciated.

Shoot the Goo into the rope when it swings back over to the left. It takes more than one shot. Also, try to aim low.
