In this game, you grab a jellybean (left click) and drag it into other jellybeans of the same color. Your jellybean grows with each touch - get it big enough and you'll get bonus points and restore some health.
Don't touch jellybeans of other colors, but drag your jellybean close to them to build up Candy Power. Hold the space bar to use Candy Power to slow down time when you're in a pinch.
Anytime you want, you can let go of your jellybean and pick up a new one. Can't maneuver your jellybean out of a tight spot? Let go and move on! Or if you've got the Candy Power for it, slow down time, move some jellybeans out of the way, and pick your old one back up!
