"ruined for general public". It means the game is too hard for general public. And stuff like accessible map at any time is more player friendly and also most common these days.
There are map consoles on each floor. Essentially though, I wanted to keep the essence of the original game. I think I've achieved that, although I appreciate that doing so will put people off. It's a free game anyway, so you don't lose anything for trying it! :o)
