You didn't come up with something new and therefore stunning, still I enjoyed playing this game for a while. The music is nice and lovely and fits to the game, which is supposed to be relaxing. The fact that there wasn't any time pressure or anything did make it calming. I do think that the amount of different colours is perfect, maybe you could add some difficulty levels though, since few seem to be unable to cope with all these colours. It would make the game more interesting as well.
I am fine with the control, but I'd ask you to include the bombs-part into the instructions.
Overall a not very original yet okay game, which has got more potential.:)
