What the remake says it changes

The store page, the official site, and the Brickworks page describe Steam app 4151300 as a full reimagining of the 2008 Sublustrum. They say it is rebuilt in explorable 3D by the people who made the original, with new puzzles and puzzles carried over in a new form. They also say the 2008 game won Best Adventure Game and Best Sound Design at the KRI Awards. This page does not compare the two from play. No walkthrough of either version is in the sources used here.
