We Can Fix This Great level to start off the pack! The only hard parts were simply placing the stackers and digger very precisely, but otherwise it's easy to figure out. I think I would allow more leeway with the platformer assignment though, as the only way to seal off the gap completely is to assign it at the very edge, but since it's very easy to determine where it goes it's not too big of a deal.

Don't Get Cold Feet One of my absolute favorites of the rank!
Very nice introduction to the slider skill and showcasing its interactions with other skills, particularly comboing it with a jumper/shimmier. I think I totally forgot that a jumper can be assigned to a sliding lemming, so that's why I had some trouble here. Once I saw that it's possible, the rest fell into place. I especially love the shimmier section underneath and using the builder staircase to get to the exit. Well done here!

Xmas in Lemmingland Easier than it looks. The only hard part was cancelling a digger with another digger, but it can be done. It might seem like a huge waste comboing a basher and interrupting him midstroke with a walker, but it's still enough skills to solve the level

Just a Slide Problem Somewhat hard level despite there being only 3 skill types. One of my mistakes in early attempts was using a platform to make a safe drop for one of the entrances, but once I realize that it could be used to seal off the gap at the bottom near the exit instead, the rest fell into place more easily. It was still somewhat hard getting the builder placements correctly so that the sliders don't go past the exit, as well as the regular lemmings being able to survive the drop. Still a nice puzzle.

Worra Lorra Jumpin' Goin' On Nice reference to Fun 29 and Crazy 15, as well as the level itself with the many platforms. The jumpers might seem like you have a lot, but don't be fooled. At least in my solution, they all end up being used! The end part is obvious, the hard part was figuring out the route to jump for the platforms.

The Lemmings Family Nice X-of-everything level to finish off the rank. I have a lot of skills leftover, but it's probably supposed to be very open-ended. I was taken by surprise that the electric orb trap gets both lemmings even at a 99 RR, but it's easy to bypass that with one of them being a floater.
