A little difficult to understand at first. The help file explains it okay, though the USER token you get in the opening room seems to be useless. You're better to crash doors until you find an OPER or ROOT token, then walk around and find all the data for cash and programs so you can re-sell them, infiltrate the SysOp node so you don't attract Heat, then disconnect, sell extra programs, and repeat that?
Either way, pretty neat amount of content for a 7DRL. There are definitely some good mechanics here which could be expanded into a full game.
