The Tower of Druaga

You control a heroic knight, who is actually prince Gilgamesh, who must attempt to rescue the maiden from the demon Druaga. You are armed with a sword and shield to attack and defend.

You move from floor to floor, which are constructed as mazes, searching for the key; this key will unlock the stage exit. Items can be found by killing (all) enemies.

A time limit is also present on each floor, and should the player take too long, two indestructible spherical enemies will charge towards Gilgamesh.
