[edit] Gameplay Overview

Players take control of a pair of characters, with one visible at any given time, and must fight through vertical scrolling stages. Numerous enemies and bosses appear and will unleash various bullet attacks that players must find gaps to squeeze through to survive. Most enemies will tend to simply sweep in to fire and won't take much to be destroyed. Bosses will usually have several phases in their fights though and possess spell attacks as last resort moves.

Players can choose between three styles when choosing a pair of characters. Balance provides equal values in attack power and spirit usage. Attack increases basic firepower but also increases the amount of spirit needed for magic. Defence reduces the amount needed to unleash magic but also drops basic firepower as well.

Players will have access to the basic bullet style attack as well as a magic attack (similar to bombs of other games) to help them through each stage. Players can switch between the paired characters, and thus alter the style of the main attack and magic spell, with a button press.

The game comes with decision points that can affect the route taken through the game, which can also be influenced by the player performance.

[edit] Detailed Mechanics

Main attack

The player's "bullet" style of attack, where a stream of rapid fire projectiles are fired towards the top side of the playing area. There is no limit to the amount this can be used and generally will be the primary means of eliminating enemies. The style of the attack depends on which character is currently being controlled. All characters move more slowly when firing though.


This game's versions of bombs. The ability to use magic is dictated by the amount of available spirit. The precise result differs depending on which character is being controlled but all magic provide the following benefits: removal of all enemy projectiles currently onscreen, a special attack activated by the paired character currently not onscreen, an increase to the size and damage of the onscreen character's main attack for a brief period and a few moments of immunity to damage.

As well as being able to be activated at the command of the player, Auto Magic will activate if the player is hit and has enough spirit for this. The effect is the same as above but this comes with several consequences, such as a much bigger loss of spirit and being dropped a rank. If a player does not have enough spirit for auto magic then they will die if hit and must use a continue to carry on, although this tends to result in bad ends.

Switch Character

Players have to choose a pair of characters to take through the game. Only one is active onscreen at any given time, and this determines the style of attacks offered. Switching between characters mid-battle can be the key to finding openings in enemy defences.


The exact route a player will take through the game is dictated by the number of rings they have. These rings can be obtained at storyline decision points, where good choices will lead to ring bonuses. Rings can also be lost, such as if the player is performing poorly. The ending reached is also determined by these rings.

While the ring bonus for decision points is initially unknown, the game will remember which decisions have been chosen before and show the ring bonus the next time you come across them.


This value is affected by things such as enemies onscreen and getting hit. The lower the P-Rate the better, as a high P-Rate will result in ring penalties and can end up forcing players along the easy routes.

Twins Gauge

This value determines the balance between the chosen duo. When one character is used this gauge increases on their side and decreases on their partner's side. A roughly balanced value is the target, as an unbalanced twins rate will result in ring penalties.


Simply tracks the amount the player has "grazed" enemy bullets (where the player character comes extremely close to getting hit by an attack without actually getting hit). Buzz helps with building up magic.
