This Sequel is just amazing! I was hooked by the story throughout the game and the endings with the Sun, the Phantom, and Mystery were nothing short of mind-bending!
(I also adore Sun way too much. He's just too adorable!)
The secret Ending was very interesting. Did not expect that about Nyx. I'm also intrigued on when Mystery became... well... Mystery since it has to be well before the Jester's and Prince's punishments. I even decided to write down everybody's title, name and real name and compiling it. Though I wonder why the Reaper doesn't have a Symbol since the Key symbol is white and it fits more with the Creator. It'll be interesting to see what you'll do!
That aside, truly an amazing sequel! Can't wait for your next masterpiece, Spark!
