What happened to other characters, such as Amy, Mighty, Ray, the Chaotix and others?
Despite not being a part of the story, they are all completely fine. As for characters like Shadow, Rouge, Silver, Blaze... They are not part of Classic Sonic's dimension. Sally? Who the heck is that?

Is the game ever going to be updated again?
No. Occasional bug fixes only.

Is there going to be a sequel? Or a prequel?

A sequel is not in my plans. As for a prequel, maybe. Nothing confirmed yet.

How did you come up with Eryon's name?
Internal talks with ShidenGaster and other friends.

Why did you remove the blood?

Eryon is not a killer, he's a corruptor. It doesn't make sense to keep the bloody mess in the game. As for the Dead Hill water, it's been replaced with a swamp-like polluted water. Even the blood in his eyes were removed.

What kind of entity Eryon is?
He's not any kind of supernatural entity, demon or anything related. He is simply an experiment who went out of control.

Will you reupload the old releases?
I know some people miss them, but I won't reupload them. They are very outdated and I fell very embarassed when I ever look at the stuff I came up with back then. Sonic and his faker's dialogue artworks, so badly drawn, being a CTRL-C + CTRL-V one of other... And those poorly programmed boss battles (a static sprite flying all over the screen), what was I thinking? At the same time I feel embarassed, I feel proud. Because if it wasn't for them, the project would never evolve to what it became today.

What elements were used as a base for Eryon's lore?

-Sonic Adventure (Perfect Chaos and the Emerald's negative energies)

-Sonic Adventure 2 (The creation of both Shadow and Eryon, by two blood related characters)

-Mortal Kombat (Not the violence, but the concept of worlds)

Sonic's world - Earthrealm.

Eryon's hideout - Chaosrealm.

Last Chance Act 0 - Netherrealm.

BONUS:

I HATE THIS GAME, IT'S NOT SCARY!

Guess what? It's not meant to be. (Yeah, someone has once told me that.)
