It's been a while since I've touched the ReadMe (or this game).
I believe you're referring to my avatar, in which case just play the game and E.G. should appear throughout.
In fact, IIRC, I programmed him to provide cheats early on since I figured most folks would be asking for cheats.
I think there are a few times where you'll need to hunt him down (as in search around) to get the alternate ending, but I'm not gonna reveal that one.
