While it didn't receive an official review yet, the site owner had some nice words to say about it:
"Holy mother of....what an episode!
Merlijn have released what is, in my humble opinion, the best episode for Dn3D ever made.
For those familiar with Merlijns previous work might have tried the three first maps in the Shaky Ground saga.
This episode contains two brand new levels in addition to the mentioned released maps.
The pace and action is overwelming and when you thought it can't be hotter around your ears Merlijn throws cascades of action and beautifully designed maps at you.
A couple of hours of pure mayhem and btw......remember to take a deep breath every now and then."
