Oh wow, this is a really good idea. Obviously the implementation is limited, but the idea to build a factory on a grid to serve an idle clicker is quite good. If you end up implementing the rest, this could be really really fun :D

too bad it's the one node type =(  I thought the control scheme was nice, that would work with a controller.

Seems like a good start, and understandable given the time constraints. There is something quite satisfying about filling the grid with stimulator nodes even in this limited prototype.

Could only make a stimulator node - could see this being quite fun with the right types of node though. Your UI was also very pretty (if a little buggy).
