It is a decadent future world built by manga artist Kazushi Hagiwara. A dungeon exploration RPG specializing in hack-and-slash. The game is full of challenging elements. There are 24 characters (8 classes), skills to enjoy combos, modifiable armaments, "NEW GAME+" to enjoy playing around, etc.
Players navigate through the dungeon using a limited "Purification Fuel" resource, which the game consumes with every step taken. This creates an intriguing tension, as players must carefully manage their fuel to avoid being forced to retreat back to their base camp. The game encourages strategic exploration, as players must decide whether to push further into the unknown or head back to conserve their precious fuel. During their exploration, players must gather enough food resources every 10 in-game days to feed their party. This food gathering objective adds an additional layer of strategy, as players must balance their dungeon delving with scavenging for sustenance. The combination of fuel management and food collection creates a unique survival-like element that keeps players engaged throughout their playthroughs.
The game utilizes an action point (AP) system, where each character can spend up to 3 actions per turn, with varying AP costs. This allows for a high degree of tactical flexibility, as players must carefully manage their AP usage to maximize their party's effectiveness. A key aspect of the combat is the "Hate" mechanic, where each character generates a Hate value that determines which enemy they will be targeted by. Players must balance out the Hate values of their party members to prevent any one character from becoming overwhelmed. This strategic element, combined with the ability to use various equipment-based skills and abilities, makes for engaging and deep combat encounters.
The game boasts an impressive roster of 24 unique characters, each with their own specialized classes and abilities. As players progress, they can recruit new characters to join their party, allowing for a wide range of party composition and strategic options. Furthermore, the equipment system offers a high degree of customization. Players can equip two weapons and one accessory per character, with each item granting different abilities and effects. This, coupled with the varied skills and abilities of the different character classes, allows players to create truly unique and specialized party setups to tackle the game's challenges.
The combination of exploration, resource management, and strategic combat creates a highly engaging experience that encourages repeated playthroughs. The game's "New Game+" feature, which randomizes the starting party and provides additional challenges, further extends the game's replayability and longevity. Despite the game's minimalist presentation, players have praised the depth and complexity of its mechanics, which offer a surprising amount of depth and nuance. The satisfying cycle of dungeon delving, gear hunting, and party optimization keeps players invested in the game's world and compelled to continue their quest.
