I haven't watched all of the videos, but since all of the original levels are up, this confirms my speculation that it is indeed possible to complete the entire game pause free. Well done, Proxima! This means that it should be possible to do for ONML too. Now I have to ask, which levels did you particularly find difficult to do for this particular challenge?
You can usually tell by which ones needed several attempts
None of them were that hard (albeit with NeoLemmix features) but from memory, the ones that gave me the most trouble were:
* Mayhem 21 "With a twist of lemming, please" -- I felt I had to do this the multitasking way because WillLem had done it
However, it's a lot easier if you assign all floaters at the start and then send out a worker lemming.
* Mayhem 22 "A BeastII of a level" -- I was expecting to breeze through this as it's a special graphics level, but that weird obstacle in the middle is surprisingly tough to navigate without pausing.
* Mayhem 28 "Mind the step" -- maybe not exactly
difficult, but it's an endurance challenge, and it feels tough because you lose so much time every time you have to start over.
Will you be covering ONML with this challenge too?
I'll at least have a go at it, but no guarantees about being able to complete it
Also, this is in no way a confirmation that it's entirely possible on Amiga, but even without the convenience features of framestepping, directional select, and skill shadows, it should still be very possible, albeit more challenging depending on the level.
In particular, I would not like to do "Just a Minute (Part Two)" without walker-only select... fortunately, it feels entirely fair to use that feature, since it did exist on Macintosh Lemmings.
I'm wondering if it's possible for the Mac's version of The Steel Mines of Kessel.
That would be extremely hard! I don't exactly remember the solution I used when I originally solved this level, but it was definitely a low route. According to Ephraim Vishniac's infamous max-saved document, the high route is possible on the Mac version; I have never verified this.
For the record, yes I tried the black and white version of Pea Soup where the peas are invisible, but this level is nowhere near as frustrating and should definitely be possible without pausing.
Oh, sure, it's possible to complete when you know where the terrain is
but when I was a kid, the Internet as we know it didn't exist, and my only source of information about other versions of Lemmings was friends who also had the game (and that was not the best source, as very few of them had gotten that far). Indeed, I remember one occasion when I visited a friend and tried to get up to "Pea Soup" to see what it was like on a colour machine, aided by the fact that Mayhem 9's password in the Mac version is easy to remember (NILEOGADIV, which happens to have vowels in the right places to make it pronounceable, and the level is "Curse of the Pharaohs" and the password happens to start with NILE). Unfortunately, we soon discovered that different versions of the game had different level passwords, so no progress was made.
