Very interesting idea. I actually wrote a bubble shooter myself. I can only imagine how hard was this to figure out to spin a grid. I don't know how you do it but you did a good job. Myself I used 2 grids at alternating positions. Trouble was that on the corners is not the same distance between the bubbles so I had to calculate, but in a circle... man that is HARD. and also spinning. Here's is my opinion make the wheel spin a little faster. Figure out a way for the balls to stick in the right place every time. Still 5 stars for this.

Real nice. Music meh.

Very nice. Love the graphics
