Well, you got farther than I did. (I didn't find the E2S14 block.) After I left the...let's say shop...I wandered around and couldn't even find my way back to anything. There's a whole lot of empty space out there and not a whole lot of landmarks. Or map.
I did find that if you press "1" you get a yellow box around...you and your blocks, I think? I literally can't tell if it's important or debugging.
