Good job with those replays. I'm glad Crazy 11 can be over and done with, but I'll update this level anyway for the sake of this challenge. As for Mayhem 10, good job using the raised double platformer there.
I have some more Havoc results and improvements.
2: 9 of each, lost 5
Forgot to attach the replay for this.
I'll see if I can explain it: It's my 13x solution with a few differences. I stoned at the start, saving three stackers. Then I used another stoner underneath the steel platform with the lower red bar and trapped the lemmings with a cloned stacker, saving one more stacker. I then did the rest of the route as normal. I freed the lemmings with a fencer.
5 and 16: 1 of each, lost 1
No replays needed here. Seems like everybody's forgotten about 5.
For 16, I simply stoned as soon as the first one appears. The skills then occur as follows: Glider, Cloner, Stacker, Platformer, Shimmier.
6: 3 of each, lost 3
Replay attached. Went the other way round compared to WillLem's solution.
14: 5 of each
Replay attached. Found a way to save the extra stacker.
20: 3 of each, lost 2
Similar to WillLem's route. Replay attached anyway.
