A word of general advice - don't take the criticism so harshly. It's just my opinions offering advice on what I did/didn't like in this pack; I'm not trying to insult your pack, I'm trying to explain what I didn't like and why (and on the flipside, what I did like and why). Maybe have a look at the level review games people were doing a while back - you'll notice that some levels from the official game are almost universally liked ("It's Hero Time" and "No Added Colors Or Lemmings" being the two most noticable), some almost universally hated (if I remember correctly, bomber timing came up a lot here) - and most crucially, some levels had wildly different opinions, for example some people mentioned "Save Me" as one of their favorites while others mentioned it as one of their most hated. Likewise, with my pack Lemmings Plus II, there's one level in particular where opinions are very polar, and that's Cunning 4 "Droppin' Bombs", which is bascially a level with an overhead bar which you blow holes in with bombers, then bomb other lemmings as they fall to create a path through obstacles. (Just for the record, LPII has the same instant bombers as in the NeoLemmix engine, even though LPII itself just uses a slightly-modified traditional Lemmix player - it's LPIII that's being built for Neo.) Some players have said it's a very interesting concept making great use of the instant bombers, while other players find it annoying and fidgety - and my own opinion of the level lies in the middle; I find it to be fairly decent but it doesn't stand out as overly special.
Anyway, I'll have your player ready within the next couple of hours or so - just got some IRL stuff to do first.
EDIT: I should mention, apart from the levels that are completely *new* in the update, I haven't replayed any of the older ones (since I solved up to the end of Taxing before you made the update). The Mayhem levels though, I played the latest versions.
