History
At some point after the release, the v2.00 patch introduced the Sequel Stage. In 2013, english patch was released by Seiha Translations[3].
Story
Introductory backstory, taken from the game's prologue:
Near the end of the 21st century, the human race created a computerized virtual world called Ill-net (Illusion Network).
It was restricted only to researchers at first, but later opened to the public and eventually became commonplace.
Additionally, development of artificial intelligences greatly advanced in this virtual world.
Artificial Human Circuits (AHCs) allowed AIs to think and feel just like real humans.
The Artificial Humanoids (AHs) using the AHCs act as guides and protectors for the residents of Ill-net.

Gameplay Overview
The game features 3 difficulty modes: Easy, Normal and Hard.
It's a rather difficult game in general though, even on Easy.
Mechanics
Buzz - it's like Graze in Touhou games. Getting close to a bullet will make the counter go up by 1.
Life - your lives. if you run out, you are asked if you wish to continue. I don't think continues are limited in any way, but using one will probably get you a bad ending.
E-Crystal - ???
Tension - Use to unleash a particularly strong attack and makes you temporarily invincible.
Auto-Tension - The game will automatically use a Tension when you get hit, should you have one. This will raise P-Rate quite a bit however.
TwinsRate: A bar that tilts to either left or right, depending on how much time you spend playing as the respective twin. This will affect certain dialog choices.
P-Rate
P-Rate (also called Erosion Rate) is very important, as it has decisive effects on dialog choices, and therefore the routes you have access to. The lower your P-Rate the better, so try your best to keep it as low as possible. Also, if P-Rate ever hits 100%, it's an instant Game Over.
Things that raise P-Rate:
-Losing a life
-Auto-Tension
-Any on-screen enemies, including mid-bosses and bosses, will perpetually raise your P-Rate just by existing.
Things that lower P-Rate:
-Killing enemies. The faster you defeat enemies, the more it will lower the P-Rate. How fast you defeated them is indicated by a number that appears on their position (e.g. "X2"). This goes up to a maximum of X4(?), which is the best result.
Known Bugs & Glitches
When the game window becomes unfocused while in the pause menu or continues prompt, the game will permanently freeze. This does not happen when in dialog, even when in the dialog choice UI
