Hey!
Umm, I'm not even sure what this is. Take no offense, good sir, but not many are going to download any demo without having a single clue as to what the plot, graphics, or anything is. You asked for help with your project, yet you've given us nothing to work with.
Also, you've just joined the forum, without any clue to who you are and are asking us to download a file that
you claim is your game. I find that a bit unnerving to download it myself.
From what I can tell from your triple post, you're kinda new to forum posting, so here's some hints:

Why not write a plot summary of your game, post some screenshots of what the game looks like, and show us what the characters are like.

Then we can see if your story needs working on, and if your mapping or whatever even needs help.
Best wishes~
