I really like the light effects of the jewels but the lighting on the ball looks a bit weird so sometimes it looks like there is a hole in it.
Scores:
Level 1 - 239
Level 2 - 209
Level 3 - 324
I couldn't complete level 4 because it is just so difficult and rage inducing despite having relaxing music in the background. I keep on falling into the holes in the third row with the zigzags.
