A hack might be finished but that doesn't guarantee it being moved to the Hacks Showcase! It needs to be of a certain standard which is determined by the moderators. I know that that might sound a bit high-and-mighty, but we'd never deny anything just because we don't like it- if it's good, it's good.
In the case of this hack, I'll have a bit of a playthrough sometime and judge whether or not it's ready for the Showcase at the moment. ;)
