I guess it would have just been too relaxing if it was just the same key over and over. I still liked this because it was fairly original. It does need some more detail, though. I also like how cool the soothing music is. One time the secret key was "Up" and I pressed the up arrow key and it didn't work. Was I supposed to type the word "Up"?
Whatever it was, ducks are pretty cool. I had no idea the duck was just going to flip over in such a silly manner. It may not have taken a lot of effort, but it's still fun. There are even some nice little details here and there, like the fish. Dang, I love that medal sound.
