Very nicely done.
This is surprisingly fun, if only to plan my shots and use physics/gravity accordingly. The music is nice and calming and the striking sounds are very smooth and don't feel out of place. The combo system keeps it interesting and adds replay value to keep building your score.
I like the black/white thing but the gradient-gray colored menu is really boring, and not much to look at. A suggestion is to give the player an option to change the colors, maybe unlocking more choices as they do well on various puzzles. You could even add effects to the later unlockables to make the bursts look different.
The game is very nice, and the best part is is that it's actually something relatively new and unique. Good job.
