I just want to add that Nutaku is not the maker/owner of Flower Knight Girl.They just have the license to host and translate the game only in their site. The real owner/maker are from DMM. As such, they have no right to port the game to other sites such as steam without the permission of the developer from DMM. It 's the same for steam, they can't host the game without the approval from both nutaku and DMM.
