Hi. About the phone game, that was supposed to be released in 2008. I saw a trailer of it and it seems there was some kind of altered story because there is a picture that Na-Yeong (as a ghost) meet So-Yeong. The developers has no connection from Sonnori i supposed and they had developed it for mobile phones like N-Gage and other Nokia phones i guess. They replaced the 3D interface into a 2D one like silent hill mobile versions (but the janitor and the ghosts are not a still image). About the slides, still finding out.
Palobina and Eun-mi's corpse at the end of the song. Just more than perfect.
There was a trailer a year ago showing whiteday on a mobile phone (not the 2009 version, full port of the PC version). This website seems to talk about that (mobile version coming....). OK, October 5 it is, we'll wait (like, tomorrow?).
