I'll make some changes to the post linked here to keep it up with recent progress to some extent:
http://www.lemmingsforums.com/index.php?topic=593.msg20328#msg20328New update to the levels, see below.
@Simon and off-topic (sorry): Even if it spoils the level, you might want to have a look at my solution to We are in this one together (attached in my previous post), as there is something weird going on when I bomb one climber slightly below another: The remaining climber reverts to a walker, hits its head, turns around and falls down - without moving into the bomber hole.
That's definitely unintended behaviour. You can file bug reports for Lix on the site
http://asdfasdf.ethz.ch/~simon/bb/forum.php?board=1 once it's back online (server's been down since this morning).
Lastly: What is the latest version of this infamous level Brickout?
That's a somewhat difficult question, as there are different branches of backroute fixes.
The latest version of the B branch (and the latest overall version by ccx) is B8-c. At stage B7.1 ccx said my solution is kinda acceptable, but not exactly as intended, and then the aforementioned comment about B8-b. There was a C branch that I think ended in C2, but it had bigger issues, so ccx withdrew it. The A branch had interesting solutions that were not the intended one. Then there's E1, a modification by Proxima.
First the good news: Found solutions to Dilemma and Stuff in the Way that feel intended (though in Stuff there are some bricks missing at the very right end of the level).
Now for the bad news:
It takes time...: Including a walker was a bad idea and one can still solve the level saving 80/80 without using the walker (though given the digger trickery involved this might be less of a problem).
Derailed Level: First I found a solution that saves 27 and can be adapted to save 28 if one is given a second walker or if one little box is added on top of the newly included one. The next totally different solution (which was a bit of a let-down) saves the required 28, but depends much on the precise digger and basher mechanics and works as well for Off the Rails...
Dilemma and Stuff are intended. I cropped Stuff at the right to remove the black space. I think its difficulty is a bit overrated, it used to be amongst the hardest levels back in the day, but now it doesn't seem as hard anymore.
New version is up,
List of Changes:It takes time: Reverted back to builder. Cutting the skill set to 3 builders/diggers each seems like a good idea now, as I know of at least one static solution building from the left that could be eliminated like that.
Derailed level: Wow, that's a pretty technical solution. I turned a crate into steel to eliminate that one. Considering how many pretty nifty solutions you've found so far, I think you'll be disappointed by the intended solution and its simplicity...
Off the rails: same modification as above
No more heroes: I decreased the width of the starting platform and checked that the level is still solvable with what I believe is the intended solution.
Stuff in the way: Cropped at the left
Tribute to Benny Hill: Time limit increased to 60 minutes
Have another Try: prettified.
List of levels that I or Nepster feel could be improved aesthetically (IMO especially the first four need it). Feel free to try your hand at these, anyone.
the giant mushroom
all over the place
heavenly skies
escape the pit: Though now that I know it's a remake from Lemmings Revolution of sorts, I wouldn't mind scrapping it either.
Babylon Fading
It's a long way up
Digging the Air (layout is good, but it doesn't fill one screen)
To Destroy is to Construct
Division of Labor
Roundabout
Solar Eclipse: I wonder, should I maybe turn all the terrain that you're not supposed to destroy into steel, basically making a steel pyramid? I somehow feel that it'd look less confusing then.
