The mod contains a tool that allow you to go trough blocks. If the tool is active you are in a Subspace bubble, so the real blocks around you are not there and you can walk trough them.

How to use:

You need to hold the Subspace Walker tool in the hand and use them (right-click) for activation.
Sneaking results in a lower Subspace and you go downwards.
Jumping bring the nodes below you back to outside Subspace so you can go upwards
To disable the Subspace Walker Tool just try to place it (left click) or take something other in the hand

The tool can be crafted in as a vertical stick:

default:diamond
default:mese_crystal
group:stick
