Dude, I don't know how you did it, but this somehow got into the Top 10 highest rated of all time! It was a fairly old flash for that matter! For however you did this, I think its strongest point was probably how the animation was so good. It's great to have stuff like this that harkens back to our childhoods. I admit that I wasn't expecting that ending with all the birds. I hope you got as good a grade in art class as you did here!
I'm guessing "Spirds" was supposed to be the names of the animals that appeared in this? You might want to also have a "Replay" button. The music was pretty good and it gave off a pretty good sense of fulfillness. I can't make many suggestions, because it was just something you did for class. It could have used a better punchline.
