This is a selection (40 of 60 levels) of my first set "jue1", produced 2002, published in summer 2003. At that time there were still no "Custom Elements" - so the levels include "only" normal R&D elements. Compared with the first release I customized the appearance, but the content of the levels didn't change.. It's something especially for puzzle - friends but I would be very pleased, if also normal BD - players would try out this set. I think, it's worthwhile. Possibly it's an inventive for you that all solution tapes are contained in the level set folder.
