The port was released then pulled from App Stores, it's not uncommon for things like that to happen. For example, sometimes apps are approved by Apple well in advance of public release and "accidentally" get pushed out if the developer doesn't fill out the Apple submission correctly. Alone in the Dark will show up eventually.
I was wondering this as well. Oh well, hope it turns up soon. It was odd that it just suddenly appeared out of nowhere with little advertising or anything anyways. I just hope the controls are okay :/
