Yes -- all my "special graphics" levels except The Land of Nightmares are more than one screen high, so it would be difficult to adapt them for LemEdit. (TLON uses graphics from the four Lemmings special levels, but mixed on one level, and therefore uses too many colours to be suitable.) However, let me know if you'd like to use any of my other Cheapo levels -- there are plenty of good ones, such as "Zorn's Lemming" and "Just a Minute (Part Five)" that don't require vertical scrolling.
