The new parts have been playtesting very well. The ice cubes and crystals from the game crafter really shine. Every time an explorer comes across these scattered in the caves, they shimmer and stand out, however, when no light is shining on them, they are completely cloaked in darkness.
The new cards used for the walls also do an excellent job in restricting light only to the corridor which is lit and also take up a lot less space in packaging and are much easier to setup.
The new treasure chest also holds and organizes the new equipment chits and ice cubes really well. In previous versions, the chest was lit from an overhead clip on light. Now it is illuminated from below giving the gold and equipment items a whole new look and feel.
