Nice work.
It's a great little game. I like the graphics and the gameplay is simple but entertaining. I did have a couple of ideas for the next version, though:
1. The game went from being impossibly easy to extremely difficult almost immediately. There wasn't a point at all where a bonus was obtainable, because in the beginning the rows were too far apart, and by the time the rows got close enough together to get a bonus, they were descending too quickly to get more than three in a shot.
2. The pieces weren't that sensitive; I had to roll over some twice for them to pick up that I'd selected them, even when I was moving slowly.
3. Little sound effects, other than the music, would make this more fun.
Otherwise, this is great, and I'm glad to see you're still working on it!
