Dark Waters: Gino and the Witch of the Black Swamp

You play Gino Castallo, a young man tortured by his own mundane existence. Another ghost-hunting expedition has you turn up empty-handed yet again, and you begin the slow trek home. On your way back you encounter a murky body of water, and the witch of the black swamp, herself, Cuca Rivers. The beautiful woman promises to show you all kinds of wonderful magic.

Everything is just as it seems, right...?
