I would heavily recommend that is included as dialouge in the game. While the mechanic is fine.
I would have given up on the game and never have read the read me file. Its not that I havent read any read me files. Its just that I have glossed through a lot of them, and their the same thing. Even yours is the same thing. Credits. Controls.
I even was skimming through previous change logs to find stuff about the mind maze. That to me was way more worthwhile than looking at the read me.
