Bashing through the Snow - I think I got this one intended. If so it's a very nice, well-hidden solution. I especially liked the idea of getting a second worker lemming separated from the crowd by using the stacker.
Enjoy Yourself - A very nice looking level! It seems that there are many ways to complete this level but none of them are obvious.
Out of the Frying Pan - I managed to save a blocker on this one so not sure if it's intended. Still a well-crafted and looking level. I liked the idea of the "cages" in the level design.
Why Worry? - This one I know for sure I backrouted
The intended solution to this one looks like it's the hardest of what I have played so far to find.
