It's very difficult to review this map pack, since I can only finish 2 of the maps (Shadesmaster's and Chambers'), as I'm far too bad at the traversal mechanics to actually get past parts of the others (sometimes starting very early on in the map...).
That said, it deserves some credit for adding more mechanics to the Re:Mobilised roster (and a not annoying slippy ice mechanic is hard to balance). Not necessarily sold on the new icy shambler though!
