Eerievale is a graphical adventure game for the Dreamcast based on the novel by Lars Hannig. It is a combination of the picture-style puzzles from games like Myst and the inventory-style adventure games more common in the genre. There is a playable demo for the Jaguar available on the Ocean Depths demo CD and a demo movie available.
It hasn't been officially canceled, but since nothing has been heard about the game since it was announced, it is considered to be on indefinite hold.
