Yea, I didn't feel like solving this level again, and so my replay is Icho's, I simply modified the end part of his solution. I was going to suggest to you to simply use your Superlemmini replay solution and just modify the end part like I did with Icho's at the end, but it looks like you did that anyway. It's easier because you avoid the whole thing of having to place a blocker on the builder staircase. It's fine in Lemmini, as lemmings can be very close but will always turn around when a blocker is placed (thus, the pass through blocker, i.e, turn a lemming into a blocker immediately from an entrance and lemmings can still go through the blocker, doesn't work in Lemmini). However, it works in Superlemmini, just like NL, and so when blocking the lemmings need to be a bit further apart in order to bounce off and turn around on one.
