GWC: If you’re a fan of Peggle, you’ll love Spring Up Harmony. It takes the same formula (shoot balls at other balls) but adds some twists and challenges to it that makes it, in my mind, a bit more fun. Instead of trying to clear out certain colored pegs, your goal is to clear out the sparkling Harmony blocks. However, the blocks come in four different colors and can only be knocked down by balls of the same color. So if the Harmony block you need is red, you’ll have to use a red ball to knock it down.
