Initial game ideea had to change was too complicated,
i didnt had all the time i planned for this.

Simple economy:
matter and energy
User can input coordinates(x,y,z) and build nodes.Fixed viewports (front,back,left,right, up, down), can be changed with keys(1,2,3,4,5,6).
Game world has random vortexes of type matter, energy (points so far).
On each node items can be built (scanner, battery, relay, junction , ray caster).
A node built near a vortex will give an amount of energy/matter.

Still have to do the building of the items.

Off to sleep
Hope i have time to finish this tomorrow after work
