Cute game, i loved the message. There isn't much interaction so I can see how some people might not like it, but it does well what it's supposed to do.
Only thing I can't say I liked is the "ending". The game kind of sets up the player to patiently wait, and having the game not tell you when it's finished feels like it can get people to wait for nothing for more time than they would want. Just a little "thanks for playing" message or something at the end would wrap up the experience nicely.
