So is this the Sequel to SpiralVortexPlay's Flash Game "A.R.I.A"?

Or is it a remake or prequel? No, really, this isn't the first A.R.I.A game made by Spiral. Google it.

This is sort of a prequel and a remake. The story has been revised since making the first game. While a lot of the initial elements are there, you'll see a lot of new things and different things focused on.
