Video Game Design Presentation

There are two things within our presentation that I feel could have been changed so that our audience could better understand our game.  One would have been a comparison of the size of our main character to other objects, and the other would have been to play the actual music and sound effects that we would use in our game.
I would have like to compare the character's size to other objects because it would have captured the feeling of the character's struggle better.  Without and reference, the audience can't understand the odds that our character must face to change himself back to his original size.
Showing the audience the soundtrack and sound effects would also have enabled them to understand the weight of the character's difficulties and triumphs.  Without sound, video games would be extremely boring, especially when you are trying to tell a story.

I feel that goals are the hardest concepts to get across to an audience because depending on the story, there could be multiple goals and multiple motivations for reaching those goals.  Without actually showing an audience a game, I feel that it is very hard to express goals unless you lay out the entire story, gameplay, rules, mechanics, and objectives of that game.  Without doing so, the audience has no interest or reference as to how the character will achieve these goals and why he/she wants to achieve them.
