Off topic: What programs are you using to make Lemmings levels nowadays? Lemmix? And how do you replay levels and make a file out of them?
I'll throw a challenge into the ring, if there's a lull in the challenges someone can maybe pick it up:
Deign a level with 4 entrances and 4 exits, set up like Havoc 14 in 4 groups so no one in one group can interact with any other group.
Level must use one of each skill. No restrictions on #of lemmings, and to be saved except that no more than 1 lemming can die in each section and at least one lemming must be saved in each section.
In solving the level, exactly 2 skills much be used to solve each quadrant's mini-puzzle.
After doing that, you must solve the level again, with the same restrictions, except you can't use a skill in a quadrant you used it in last time. So if you used a blocker and a digger in Q1, you have to use two of the other 6 skills for the 2nd solution.
