It seems that Ryonamon has become the Warcraft Adventures of guro gaming because of it's quality and current status!Further digging revealed that a demo/alpha version of the game exists and at this point it is very valuable to collectors but I'm sure it will surface eventualy so keep your eyes open.It will be awesome if gurochan will be the first place it becomes available.
Here is recorded footage from the the actual game:
