Well I was actually talking about the PSP release with the font part! It was blatantly obvious it was "Chiller"
Was it? I didn't realize at all. It's a font 5pb picked out themselves during localization programming, and as far as I knew, they made it. If they adapted it from Chiller, it at least required some heavy editing, as the kerning was initially way off -- I can't seem to find it now, but the very first screenshot we ever released for the game (Ayumi in the classroom, talking about how delicious Satoshi's reaction was) showed this pretty clearly, as the space between each letter was wildly inconsistent.
Whether or not it was Chiller, though, I thought it looked DAMN GOOD in the context of the game. I can't even imagine playing that version of Corpse Party with any other font at this point. It's probably my favorite font choice ever to be featured in any game XSEED's released since I started here.
