:lem-mindblown:
If you start assigning shimmiers repetitively right at the moment when the slider reach the bottom, he slides into the wall.
Whether the wall is steel or normal terrain doesn't matter.
NeoLemmix's logical counterpart to wall crawling from Lemmings 2: The Tribes - downward instead of upward :D ...
Fixed in commit c068c98. This will be included as part of V12.13.0 - the workaround in the meantime is "don't abuse this glitch, your solution does not count as valid if it uses this and your level is a troll level if it requires this" - due to the need for an RC phase to properly evaluate whether there are any side effects.
