you see i'm still mostly thinking in terms of 'conventional' solutions...
There's nothing wrong with that, conventional solutions work just fine for most levels.
It seems reasonable that the sliding glitch is going to see a lot of use in this type of challenge. There's a tendency for levels to start at the top and work downwards (the alternative usually being heavy building, which would be boring to do all the time). Reversing those levels means you start at the bottom and work upwards. The sliding glitch can be a very skill-efficient way to move lemmings upwards. It makes sense.
Continuing on with more improvements to
Wicked:
5: Annoyingly, I couldn't quite pull this off either. At most though, you can get by with
1 added builder.
6: Possible. To start with, I used sliding to get halfway up, but it turns out you don't need to do that. This solution also uses no bombers at all
(I did 10 since my last post, but you beat me to it. Good find
)
11: Me and my sliding glitch
. It's possible with the regular skillset.
16: Pretty clearly impossible with the regular skillset, here's a fairly simple method using
5 extra skills, 1 blocker and 4 builders. I haven't looked too hard for other methods, but nothing stands out as a better option.
18: Not too difficult, you just need to stack some bridges on the right to contain the crowd.
19: This one works out very nicely with
1 added blocker.
For 14, it looks like you need extra skills just to
reach the left wall, let alone slide up it. It might still be the best option (as far as fewest added skills), I don't know yet.
For
20,
I suspect the most skill-efficient solution involves sliding into the exit, so it matters not that it's buried
EDIT: Changed my mind. I found a solution with
1 builder added, and no glitches. There's a 'spare' digger, so it still doesn't matter that the exit is buried
