I have a suggestion for later verisons. Make it so that Neutrons, when they pass through BHOL, the hole inverts and becomes a WHOL, and visa versa.
I discovered that insulator doesn't insulate spark to PSTN. e.g. If i have SPRK running down PSCN and it goes past PSTN 1 pixel away from it when there is INSL in between of them, the SPRK will power the PSTN. Same happens with any other conductor METL,TTAN,NSCN,INWR etc.....
I am using the pc version. I spelled it right.
I found bug: doesn't absorb all fast moving NEUT/ELEC when go to 2px thick VIBR.
