i ADORE your one-shots! they're so amazingly awesome. keep going! :D i'd love to read more.

It is amazingly refreshing to come to this fandom and find something that is NOT slash/yaoi/call it what you will.
This is also quite interesting in its own right. Drabbles are fun, especially when they tie characters together this way.
And at this point, I have just one critique:
It confused me when Tifa first crashes into Cloud and Zack. I realize you said it was dark, but if they could make out Cloud's hair in what light existed, she should have seen them if they were just standing there. I'm wondering if there might have been a way to make what happened clearer AS it happened, so readers don't have to pause when they're told who Tifa tripped over and then go back to the tripping part.
Thank you, and have fun writing! (In between real life's demands, of course.)

I really liked what you've got so far; it's a cool idea do have a sort of pre-kingdom hearts setting. Well anyways, keep up the good work, I'd love to read more one-shots.
