Player
You control the player in his quest to escape the dungeon. He is limited to one weapon, his Photon Light Pistol, and he is only able to fire it upward. He has a health meter which is displayed at the top of the screen throughout the game. At the start of the game, the maximum value that your health can reach is 1000, but certain items can increase this number. Lost health is regained by destroying enemies, most of which die in one hit. Health is lost by touching enemies or getting hit by their projectiles. If his health meter drops to zero, he will die and the game will be over.

In order to make his way through the dungeon, it is necessary to collect three colored stones. Throughout the dungeon are shafts that connect various floors. These shafts are coded red, green, and yellow. If the player does not possess the corresponding color stone, he will drop to the bottom of the shaft. If he does possess the right color stone, he will be able to move up and down the shaft at his discretion.

As the player, your primary challenge is to make your way through the labyrinth-like floors, and avoid getting lost as you proceed. Additionally, some passages are obscured from your view by fake walls, so you must learn how to properly identify such walls. If you intend to play through the game without using the provided walkthrough, it is important that you map your progress and keep a record of which passageways you have explored, and which ones you have yet to examine.
