Gentle 5: 0:36.41. I went a slightly different way to finish by walking over the first part of the grid and then bashing down.
Gentle 8: 0:18.35. This was a relatively straightforward improvement, not that I could physically pull it off though. After seeing the solution I removed the blocker and re-assigned all the lems in the appropriate frames with a text editor.
Quirky 12: 0:33.88. The old replay was another one that started with an instant blocker. I realised that if any replay creates this sort of situation, I can just simply use the text editor to remove the blocker and repeat the process of reducing frames for every skill assignment. This replay is trickier because it does has a few RR changes; so I'll need to check the SPAWNED count, but I don't think that would've affected anything else too badly.
Quirky 13: I was able to pull off the exact same time; just assigned the right side digger earlier.
Quirky 21: 0:56.53. Simply took 46 frames off every assignment here. Must admire the lovely solution too.
Zany 20: 0:46.88 (13 seconds better than the original
) Once I figured out who was able to do what, I simply assigned the worker for the first lemming.
Manic 18: 1:01.41. I went a different way and ended up saving much more time! The time could be optimised even further to accommodate crowd release, but it could be a hassle, particularly with how many lems you'll need in the digger's pit.
Lunatic 10: 1:39.18. As well as optimising the frames, I was able to move the starting point of the crowd release builder at least 1 pixel to the right so that it doesn't bump into the wall unlike last time round.
Lunatic 16: 1:46.12. More frame reduction editing here.
Lunatic 17: 1:10.00. Like Manic 18, this level still needs RR optimising to put the climbers in the same place, but otherwise I think this is the fastest way to get them home.
