Description

Plot Point: 

After a huge earthquake shakes up Gensokyo, Iku Nagae ventures out to find the source of the blast, using her incredible fever skills. 

Gameplay:

This is a cross between a bullet hell and rhythm game. This game is unique because of Iku’s fever ability, which allows her to graze through large waves of bullets safely without getting hit.
It’s ideal to press the key to the rhythm of the theme playing for points, extra lives, and efficient gameplay.
Iku has three shot types: Straight, which shoots directly in front of her, Wide, that shoots at a larger angle, and Rolling, which shoots in a circular motion around her. 
She also has three spell types: Bomb, which shoots a short range projectile that explodes on contact, Thunder, which zaps the closest enemy to Iku in a straight line, and Kaikou, which sends out homing projectiles onto her enemies.
When not in use Fever Time will regenerate by itself, but players can speed up charging by destroying the enemy and collecting dropped items. If player never loses a life since the beginning of the game and have maximum lives, the player will enter Revolution Mode which is basically similar to Donpachi's additional multiplier score sytem. If the player manages to unlock all secret bonus requirements on a stage, an alternative path can be traversed.
Iku can choose any combination of shot and bomb types. In addition, Iku has 5 possible movement speeds, selectable before beginning the game.
The player can earn achievements, depending on each level you complete  and the difficulty. In addition, there are secret achievements for performing  specific actions in each stage. After completing each stage, a boss stage will appear. Survive their attacks to make it to the next stage!
