retnuh's comment is right on point. Volcano level is impossible -- dropping a block on each successive pass of the crane and still can't top 290. Coins should be able to be spent in a shop to upgrade your crane, the timer, the block accuracy -- something...anything.
You should have each of the planets in the background at different levels. Once my score got up around 4000 or so, it was just black with an occasional ufo.
I like it - it's a game you'd see in, like, Brain Age or something. My only suggestion would be the ability and go back and edit a previous face (when the multiples show up) in case you remember a detail but have moved on.
