What skills can't you live without?

Here's a no-digger solution to Havoc 18.  It's actually pretty straightforward except for a well-placed bomber to ensure the crowd doesn't wander astray while the final bridge is underway.  The attached screenshot should provide sufficient detail on the solution.

This just barely works, but Mayhem 25 has been reduced to 4 builders.  A detailed solution and screenshot are provided below.

Solution

The first lemming builds a couple pixels back of the edge (he needs to lay 7 bricks before turning on the steel).  The second lemming dies, and the third lemming becomes an Athlete and climbs over the steel wall.  After the first lemming turns, he digs in a pixel-precise location, such that he just barely takes out the edge of the steel below.

Let the Athlete drop down a level and then have him build just before he falls a second time.  The 7th lemming out builds as soon as he drops into the digger's "tunnel"; this bridge should close the gap just in time to save the 10th lemming.  Meanwhile the Athlete builds over the next gap, starting from the very edge.

The lemmings will drop down to the stairway below and to the left of the exit.  Block off the gap to the left of this stairway, and send two climbers up toward the exit (one is the Athlete that was assigned earlier).  The first climber blocks shortly before exiting, and the other mines immediately after turning off the blocker, freeing the crowd.  Now bash to free the blocker, and everyone can exit.  Assuming everything was done right, you'll end up saving exactly 90% (the minimum).

More improvements on Hail 11! Thanks to a brilliant trick involving miners, blockers and a diagonal ceiling I can confirm the result for this level has been reduced.

Replays attached below (Although the other one is rather trivial once you know about it)

The result is now 3 builders & 1 miner.

Some more Hail improvements with replays attached (I'm afraid. )

7: 13 builders
8: No bashers (5 builders still needed)

And also attached, a solution I've always wanted to find a replay of but never did: The 4 builder solution to Fun 16.

It's interesting to compare Luis's results for PSP Lemmings (played on the actual PSP version) with our results from the NL conversions of the levels (which, I believe, are based on Luis's Lemmix conversions, although I have made small tweaks to a few levels).

Obviously, some results differences will be because of the different engines (e.g. the shredder in Level 33 requires an extra builder to build past in NL) and some might be because of inaccuracies in the conversions. However, some differences may be because only one person has attempted this challenge on the PSP levels, and it's easy for one person to miss things (e.g. Eric's post here suggests that the digger is not required on Level 36).

So it would be interesting to go over the PSP results and try to improve them -- and also to see whether any of the cases where the PSP result is better than the NL one are because we missed something when playing them in NL

[EDIT: Already discovered two cases where Luis caught something that we missed -- Levels 15 and 21.   And thanks to Pooty, all the remaining cases where the PSP result was an improvement on the NL result have now been confirmed on NL too!]

[EDIT 2: Also, the adding up of the PSP results was wrong on a few counts   I've taken the opportunity to correct it, taking Luis's results for the individual levels as correct for now, even though I suspect that several of them can be improved.]
