Man, what are those JP peeps on about? Why would anyone need a super easy difficulty?
I did a playthrough on Normal Mode on 1.03, without MTool, just screenshotting and OCR-ing a few things here and there. (Particularly that one succubus in the cafe that tells you about the floor gimmicks.) and even when I barely knew what anything did, I was still able to beat the game and get the good ending...
Granted, I suppose I'm more used to RPG gimmicks than most peeps.
Well, experiments aside, that playthrough definitely made me all the more eager for a TL...
