I am currently trying to gain info on a Visual Novel Ever17 ~CrossOver Impressions~ I dont know too much about it but I do know it features characters from several KID's visual novel (such as Ever17) and I happened to have come across a copy of the VN. Does anyone know anymore about it.
(If you are interested I can submit a download link of the VN)

The only thing that VNDB has about it is that it's an unofficial work by VR Express.
