fyi you can turn on English ui/tutorial by going into setup.ini in the game folder and changing the language from jp to en, this doesn't translate any of the japanese text from the story however, but it will help play the game itself, this is also where you can change the full screen setting to 'true'
edit: i just realized you can also open up config.exe to change these settings, do that unless you want to feel like a cool programmer/hacker type dude for about 5 seconds.
