Game Features and Gameplay
Active Animation Adventure
In order to bring out the appeal of characters, animation aspects have been developed to be included in event scenes so that things such as facial expressions change in real time.
As further examples:
-Accessories, hair, ears, wings move
-Facial parts such as eyes and eyebrows move in tandem as emotions change
-Mouth movements in line with voice
-Changes in poses as event scenes necessitate
-Visual expressions from anime/manga (! icons, blue vertical lines when disappointed, etc)
Unconcious head movements and breathing, smooth changes in emotional expressions help bring the characters to life.
Game Flow
The game primarily consists of events, dungeon searching, and battles.
By examing debris that flows into the world map, you may be able to enter a dungeon, encounter events, etc.
In dungeons, your primary goal is to destroy the gravity well of that particular debris. After finding the gravity well, eliminating the boss guarding it, and destroying the gravity well, you will have a limited time to exit the dungeon. Upon destruction of the gravity well, the space time continuum in the surrounding area becomes unstable. As a result, various rare items will start to be drawn into the local area. If you spend too much time collecting the rare items, you will be unable to escape in time.
If you're unable to escape, instead of being "Game Over", you'll stuck drifting about in space. At this point, sandwiching chat events between party members (and bickering events on occaision), you will need to wait for help from the likes of aliens. Of course, they won't help you out of good will and you will be required to give up earned money and items.
After you've cleared a set number of dungeons, the story will progress with various events and previews being sandwiched (see Cross Edge) in between.
Sensation
You will have search magic called sensation to search the local area for hidden gravity wells. If no gravity wells are nearby, as a hint, a streak of light will go flying in the direction of a gravity well. In addition to this, you will be able to find hidden rare items and hunting points with sensation, but due to the limit to the number of times you can use sensation, you will need to conduct your searches efficiently using the hints as mentioned above.
Hunting Points
Hunting points are locations which are densely populated by monsters. By searching for them, you'll be able to enter into battle with them in rapid succession. After a set number of battles, the hunting point disappears and your encounters with monsters become non-existant, temporarily, making it possible to search further without interruptions. In addition, by using hunting points, you are able to gather mats for crafting from monsters more efficiently.
Materials
You will be able to use materials gathered to synthesize items used to power up your characters.
-In the demonlord scenario, you can use materials to create powerful monsters. Then, by defeating the monsters you create in the "arena", you are able earn items which will increase your stats.
-In the goddess scenario, you can use the materials to create meteorites, which, when multiple are equipped, will allow your characters to gain new skills depending on what combination of meteorites are equipped.
Furthermore, in both scenarios, there is a system called "Mana Graphics" that utilizes these materials.
Mana Graphic
By drawing various designs on your weapons, you will be able to strengthen them. While you're able to change mana graphics based on the enemy weaknesses to exploit them, changing the mana graphics also results in visual changes during battle as well as a variety of different effects.
Excite Encounter
If you spend too long searching a dungeon, a powerful monster (excite monster) will sometimes appear. The encounter won't be sudden. Rather, the monster will gradually chase your party down, with scenes indicating that the monster is doing so. While it is possible to safely escape, if you take the time to prepare for, and defeat the monster, you will be able to obtain rare items and such as a reward.
About the Battle System
Time Encounter Battle
You will have a limited amount of time in the attack phase. Further, attack skills are associated with AP (action points), and the amount of time you have remaining will decrease with AP consumption. The stronger the attack, the more AP will be required to use it. Thus, in order to move the battle forward in your party's favor, you will need to adapt your battle strategy as the situation requires.
One Button Skill Link
The basic attack skills are divided into 3 types: combination attacks, heavy blows, and magic, all of which can be executed with 1 button. By executing these skills in various orders, you will be able to execute stronger skills.
Fury Chain
Before your attack phase timer runs out, you can swap to the next character and maintain a chain of attacks. In addition to in-battle benefits, such as increase in attack power and filling of the image gauge, this may also result in additional XP or money earned as well as other post-battle bonuses.
Furthermore, by meeting certain criteria by chaining, you will be able to execute combination attacks between 2 to 4 characters.
Image Guage
The image guage will fill by various means such as attacking or exploiting an enemy's weakspot, and will ultimately allow you to unleash mana graphics in-battle.
By unleashing Mana graphics, you will be able to do the following:
1. Unleash character specific special attacks
2. Recover HP (it is possible to recover beyond your Max HP)
3. Deploy a shield that will reduce your damage taken
Action Ability
This will allow you to use various support skills such as using items, recovery, and stat boosts. You will, for the most part, be able to freely set the various support skills between rank 1 and 4, with rank 1 aspects being usable immediately and further ranks requiring progressively more time to become usable.
Because of the limited amount of time during the attack phase, skills which are used frequently can be set to a lower rank whereas aspects which are used less frequently can be set to higher ranks. The player can adjust these to suit their needs and style of play.
Soul Barrier
By exploiting weaknesses and making good use of chains, it will be possible to destroy a monster's soul barrier. A monster whose soul barrier is destroyed will have various changes associated with it. From the basic enrage where defense goes down and attack power goes up, to a change in weakness, change in attack strategy, or change in items that are dropped, destroying a monster's soul barrier will result in quite a few situations where you will need to actively alter your strategy, increasing the depth of battle.
