Juggler is a neat little diversion that I would categorize as a gravity based game of mouse dexterity. Mark Vertegaal of Cold Tomatoes obviously understands clean design and smooth gameplay, and Juggler offers just that.
The goal is simple: You control one paddle (ala breakout) while multiple balls bounce in sequence. You must maintain the balls in the air like a crazy one armed juggler. You are given four lives, and a goal of 1000 points bumps you up to the next level. With each new level comes increasing difficulties like more balls, smaller paddle, etc. Control the paddle with the mouse and try to stay air born as long as possible. A quick glance at the high score board may discourage you, but keep going. Trust me, it's worth it.
Analysis: I personally have a great affinity for accurate applications of gravity in casual games. As a juggler myself, I find that I am often attracted to gravity-based games (such as lunar lander and the like). But when a game tries to imitate gravity and gets it wrong, it sticks out like a sore thumb. And unless there is really engaging game play to make up for it, that alone can turn me away. Juggler provides that satisfying flow of gravity impeccably.
Everything from the animation of the balls, to the delicate control given by bouncing on specific locations of the pad, to the humorous level titles, makes the game a pleasure. It offers plenty of replay value and is simple to learn, though with enough of a challenge to keep you interested.
Hint: I find that nudging the balls toward one of the side walls helps a lot. Try keeping their trajectories as vertical as possible.
