Labyrinth of Time The Labyrinth of Time is a bonus dungeon in the PSP and iOS versions of the original " Final Fantasy " . It consists of various floors , each one containing puzzles that must be solved on time for the player to be able to proceed . If the player fails to solve the puzzle on time , a dense fog will invade the area , sapping the party ' s HP and increasing the encounter rate , and the player will unlock the red seal of the floor when completing the puzzle , which is a sign of failure . Successfully completing a floor will allow the player to unlock its blue seal ; either way , a passage to the next floor becomes available . Stages are chosen at random on each playthrough . If the player is able to reach the deepest floor of the dungeon , they will face Chronodia , Master of Time , the superboss introduced in the PSP version . Chronodia ' s strength depends on the number of blue and red seals unlocked by the player . The more red seals unlocked , the weaker Chronodia will be , and the more blue seals unlocked , the stronger Chronodia will be . This dungeon is located in the Chaos Shrine and can be first visited when the player defeats all four Fiends for the first time . The player must visit Cornelia first and speak to the mysterious man in the center of the town . Then , the party should head for the Shrine , where they will observe the man entering a hidden room that serves as the entrance to the Labyrinth . Floors . Before entering each floor , the player meets the Light of Time , who allows the player to trade abilities for time . The maximum number of abilities to surrender ( and their nature ) depends on the floor to be entered . After the transaction is done , the player will enter the floor , which contains a puzzle . The black - caped man may randomly appear as the player enters the area , and offer a random service , such as giving items , giving more time , or even allowing the player to leave the dungeon . After that , it is compulsory to solve the puzzle before proceeding deeper in the Labyrinth . Most of the puzzle areas are devoid of enemy encounters . Modern Maze . In the Labyrinth of Time , the floors ( and their order ) one gets at each playthrough are randomized every time , although the first is always taken from a set of floors called the Modern Maze . Usually , they are the easiest puzzles and the random encounters should pose no threat . Original Chaos . Starting here , the player might have a harder time getting through . The puzzles are harder , possibly longer , and usually require several abilities to be traded for time . As such , they make the random encounters ( with usually powerful enemies ) very dangerous . Netherworld Crypt . This is a powered up version of Original Chaos . The first floor of the Netherworld Crypt ( the Inner Sanctum ) allows the player to fully recover HP , MP and status ailments , and to leave the Labyrinth of Time . This is the only time ( except for the black - caped man who might give the opportunity ) the player can leave . Otherwise , Chronodia has to be defeated to avoid getting a Game Over . In the iOS version , if you close the app after reaching the Inner Sanctum ( while still in the Labyrinth of Time ) , you will be brought back to the Inner Sanctum upon selecting ' Resume ' when you next open the app .
