Repetitive. Moreso than usual...
While the graphic quality is nicely done, the music seems a bit too grand for the content. It's almost like having Bach compose an entire symphony for an Arby's commercial. The gameplay shows promise in the first couple levels, but I quickly discovered that all I needed was the basic cloud attack through the entire game. The upgrade system is almost impractical, if only there for some temporary amusement with the other skills.
The other feature that confused me was the ability to jump. Nowhere did I need this ability, other than perhaps ONE time, in which there was also another way to get around the obstacle without jumping, as well. You also can't jump with your sister in hand, so even if you were to jump over an enemy, you endanger the kid. While on topic...you should NEVER even have to move the child, for the center of the field where you begin is the ideal place to start and finish the level. Just fire clouds and you're done.
Enemy versatility (in more ways than cosmetic,) practical upgrades, and definitely some difficulty and gameplay increase is necessary. However, again, the animation was smooth, and that was nice enough.
