●4 Difficulty Levels
This game offers 4 difficulty levels:
・Easy (HP3, Red Oni and monsters move slowly)
Recommended for those who find action games challenging.
・Normal (HP3, Red Oni and monsters move at normal speed)
Recommended for first-time players.
・Hard (HP2, numerous obstacle gimmicks placed)
HP is reduced compared to Normal, leaving no room for error. Furthermore, numerous obstacle gimmicks are placed, demanding more advanced control skills.
・Nightmare (HP1, numerous obstacle gimmicks, darkness, map hidden, obstacle crystals placed)
The highest difficulty in this game. HP is reduced to 1, leaving no margin for error. Enjoy heightened tension amidst numerous obstacle gimmicks. Furthermore, the surroundings are plunged into darkness, making it difficult to grasp the entire stage. Additionally, the map and emblem locations are hidden, forcing players to memorize their own position and the locations of emblems they've collected. To make matters worse, hindrance crystals (animal-shaped) are added to the paths needed to collect emblems, forcing players to backtrack and tormenting them. Players will likely find themselves lost and confused, unsure where to go. Can you overcome this trial?

● For Those Struggling to Clear
You can change the difficulty level at any time by examining the “Light Blue Crystal” found early in each stage. If you feel this difficulty isn't right for you, feel free to adjust it anytime.
