Black Magic

"The player's objective is to find the six eyeballs scattered across the land which are needed to pass the Blind Statue. Every time the player picks up one of the eyes, a new batch of monsters populates the land making travel more difficult. Once the eyes are placed back in the Blind Statue's empty sockets, a message will appear explaining how to end Zahgrim's rule over the land once and for all. It is achieved by entering his castle, a wicked and difficult maze of traps and monsters." Source: Wikipedia, "Black Magic (video game)", available under the CC-BY-SA License.
