adding sound and animation

Write a blog post about how adding sound, animation, and interaction has changed your game design? Has it greatly changed the design, or not at all?
when I first started i thought i new exactly how i wanted things to be and it was pretty much a done deal. Well after adding a few things i found out and i have changed a few things. I want to keep working on this idea. and to continue adding the backgrounds and more selections to the game. The animation was harder than i thought it would have been. The music was not that bad. Writing the action script and making it all come together and watching it all unfold is great. To see something that you have created and watching it work. Still cant believe it. Cant wait till im done.
