Just discovered this web site and am delighted, but no help to be found here :( Deep Blue Sea 2 is about to be released and I'd love to finish the first one, if possible. I'm on the last level and just can't get the folders moved to the two center slots to empty out. I know the techniques to use, but always get timed out. Maybe there is a faster approach. Any suggestions?
