"A Long way Down" by t3tesla (originally titled "Suicidal Tendencies") from Revenge of the Lemmings was a favorite of mine, in the snow set, it could be decorated to be more Christmas. I thought this one was tricky but I don't think I could give it a gold talisman. [The hardest solution can't really be enforced with the talisman limitations].
Is this the level you were referring to? Think it was this one that had the name changed a few times.
