Solomon no Kagi

The main character, named Dana, is sent to retrieve “Solomon’s Key” to restore the world to light from demons that were accidentally released. The object of the game is to advance through the 50 rooms of “Constellation Space” by acquiring a key to the door that leads to the next room before a timer runs out. Dana can run, jump, create or destroy orange blocks adjacent to him as well as create fireballs to destroy demons. The orange blocks can also be destroyed by hitting them with the character’s head twice. Along the way Dana can acquire items to upgrade his firepower and extra lives as well as items that award bonus points and unlock hidden rooms. With certain items, Dana must make, then break blocks (sometimes in a certain manner) to make these appear.

In the FDS version, a “GDV” (Game Deviation Value) score also appears at the game-over screen. The score uses a weighted composite of several factors (like levels completed, items found, time and points) which gives the player a good idea of how well the last game was played. The higher the GDV, the better the game.
