Sorry if I spoiled anybody's fun, but since I work in internet security, I tend to be a little zealous when it comes to illegal content online.
Besides, even though there is little chance this game will get released outside of Japan, illegal downloads would hamper what little chance it did have of being released otherwise. Look at what happened with RPG Tsukuru; it took four incarnations of the program before an official English release came to be.
In addition, if you tick off the wrong companies, they could theoritically have this entire site shut down for one link like that (although I don't see that happening as this is a Doujinsoft group, but I digress).
Back to the topic at hand, I haven't tried the demo yet, but I'm liking what I see so far on the videos.
