these two levels both use some rare tricks and are, at least at the moment imo, pretty hard levels and will be in the final rank most likely.
hints:
Cliffs: remember that some skills may be just a decoy. I can only remember seeing this trick in one level by Pieuw.
Obstacle 2: This trick was used once before in MobiLems1 but besides that I've only seen it in 1 level by ccexplore. It's a clever building trick to isolate one lemming.
Five easy steps: the intended solution here is a little similar to "No added colors or lemmings"
Over the top: the big thing here (unless there are backroutes) is the order in which you send climbers around to do the work [and use the cloners].
Over the top is my first attempt to make a level with pick-up skills. Well all of them are my first attempts at making levels with the new features so I have no idea how they're going to turn out.
