Niiiiiice! It uses the Cave Story events to good use, and everything makes sense. Great job yo..

Heheh, the ending...
Wonderful work, fits perfectly to the storyline. Only one thing is seemingly wrong, Quote or Curly didn't kill Miakid, It was someone else. (Arthur?)
Great, this was fun to read.

*reads ending* I see what you did there. :3

The ending made me laugh. I myself had always thought Quote had a thing for Curly, too.

Now about the rest of the story...

Nice job weaving Quote's thoughts with the present-day story. Besides the end, the other part I loved most was at the beginning, when you made a comparison between Quote and Curly's personalities. I thought you were spot-on accurate.

"Curly Brace was the radiant sun, with her golden metal hair that flowed with the wind, and he was the moon that could only borrow her radiance."

Love, love that sentence.

I guess the only minor issues I had were some of the names, which is probably a result of us playing different versions of Cave Story, but none of these were major enough to make a big deal out of.
