The soundtrack pairs along very nicely with the game. Overall, this game has a lot of potential. However, it does have a few problems. The main problem I’ve seen is that whenever I hit a diamond to collect it, it explodes into red light and makes a pop sound. This is incredibly distracting because the path for the ball to roll on is thin enough, and when the light explodes from the diamond, the ball seems to momentarily disappear under the light. It’s even more problematic when there are multiple diamonds in a row or sharp intricate maneuvers you really have to be precise with and you can’t properly keep track of the ball. The noises from the diamonds are also distracting because you rely heavily on the beat of the music to play and make turns, but the noises can throw you off. Other than that, the app is decent and I’d rate it 3 stars, 4 stars if there wasn’t a problem with the diamonds.
