"You will, several times during the course of the game, be presented with Japanese characters without an English translation. Don't panic! You do not need to know what they say or mean in order to escape. You may have to remember or identify the characters when solving some of the puzzles, but that's completely doable without an understanding of the language. Unfortunately, however, for those of you running Linux the game may be unplayable; it seems that there's one code (that changes every play-through) that Linux has a text display issue with and so will not display. Sorry, Linux guys/gals."
