It's a great concept, and I enjoy the style, but there are some issues. The movement of the eggs themselves is sometimes erratic, and moving the bars can be a chore, particularly if you're moving a chain of them.
The controls are a little off of what I've come to expect in this kind of game. In particular, it seems to be too much of a hassle to aim the ball in the direction you'd like. Career mode is a nice thought but ultimately unnecessary.
