At first: realy nice. Even if it is simple, for one or another, maybe this is the nice thing on it. There are cuddly drwaings and good feel settings at the beach and the sounds remind me a little bit of when I was younger.
I think more levels would be nice because its quite short. But even this is in a way good cause the player is immediatly hungry for more.
Perhaps you can include some Comics between the levels so that you can "stretch" the experience ;-)
