You can take my advice, or leave it.
I'm giving you a 3 because the title could be comprehended by the story. The intro before the play menu makes no sense-take that out. Also take out the big KM, that's really disturbing. It was also very corny, and I like corny because it makes up for beginner;s trying to make a superb flash. I am a beginner myself, it is tough.
You do not need a book. You need to use your imagination. Think about what people look like and how they move. I know it's a cartoon, you don't have to give your characters faces-I don't in mine, or at least yet. I liked that you used text box's, many beginners try to write things out with the brush/pencil. Think about what the characters are going through to accomplish goals-this will ultimately help your plot in the end.
Take the time, and your 3 could turn into a 4,5,6,7...etc. GJ, better than most beginners.
