Okay, finally played this pack during yesterday and today. I remember playing this pack when it first was released for Lemmini back in 2014, but somehow I never commented your MobiLems topics. Okay, I've for sure commented your levels in Lemmix/Lemmini Level Pack Topic, where you've released your 10 level Lemmix/Lemmini packs that are an essential part of this big pack.
Your levels are quite classics already now, people know them. They're known from the aforementioned old packs already, some of the were in Revenge of the Lemmings, and a large part of them are in Lix community level set. Very much deservedly is all I can say. MobiLems goes better and better towards the end after a bit slow start with some X-of-everything levels, but almost every single level at the last 2/3 of the pack felt magnificent. I find it very hard to name my favourite level of that steady quality bunch, let's say Flapdoodle18: The Transit Timing Variations, Brouhaha17: Tres Hombres and Heinous15: If a Lemming Falls (part 2), for some examples. Many level pairs were really strong also, I don't like too much level pairs with an X-of-everything level with a repeat level (there were some of those, too), but level pairs with two different puzzles, those were pretty slick!
For a possible update, think about time limits, they seemed really random, some levels didn't have them, some levels had them but had really much time that you couldn't use all of it, and then there were tight time limits that prevented backroutes, which is of course great. Some typos still in titles, Flapdoodle11: Portait of a Lemming (Portrait) and Brouhaha1: The Final Sacrafice (Sacrifice).
Needless to say, I am so eager to play MobiLems II in the future, if and whenever that moment comes.
My solutions are attached.
