He was putting things on DLSite. I don't know really much, other than he's been inactive for a long, long time. He sort of abandoned things. A month back or so, someone posted that he's working on it again. I don't know where, but I completely have not seen evidence of it.
It's a shitty fullscreen in that it changes the resolution on pretty much everything, and sometimes some programs and Windows and stuff will just decide not to change back to the resolution it should be when you drop the game. Worse, some people prefer to have a larger screen without using the shitty Fullscreen option, which is distorted, and use programs like Sizer to resize the window so they can keep up a guide, or some other porn thing, or something else in the background, but XP was coded in such a way that while the window gets bigger, the usable screen remains a quarter of the size of the window.
