For some reason I really liked just kicking the balls around, and I don't know if it was an intended feature but I also like how you can kind of "dribble" the balls, like they will get stuck your your character sometimes and you can easily change their direction. One thing to note though is that if a ball reaches the top of the screen the player is unable to reach it. Since you don't technically need all of them to pass the levels it works out fine, but the edge of the screen is something to keep in mind when developing future games.
