For someone like myself who has taken a break from Lemmings for a while, this was a great pack to get back into it a little! 
Still easy enough for me to finish in one sitting, but not trivial - I prefer this much more to levels that leave the player too many degrees of freedom (such as most X-of-everything levels).
Replays are attached. I was positively surprised to find they are now being saved under the level names, even when playing the levels in the NeoLemmix player.
So far, this only happened whenever I played individual levels from within the NeoLemmix editor.
