I’ve got some of the basics working for No Crypto For Old Men. Here’s a screenshot:
On the left is the “map” of the network you are currently attacking. You are the “@”, naturally. The dots are a “conduit” you can follow to other nodes in the network.
On the right is the “terminal” where you type commands. Eventually, there will be many terminal commands, and one of the “treasures” you’ll be able to find will be new terminal commands.
Both of these are working, although both maps and available terminal commands are quite boring at the moment.
