Pretty interesting concept... but I find it kind of slow for my tastes. You have to both create flower, then match them correctly to clear 4 blocks, and the correct pieces can take a while to show themselves. And if you've created the wrong flowers, I guess you're out of luck? Then again, it seems you're supposed to play for the score anyway.
Nice animations though, they felt satisfying. Also, not sure if that's intentional or just bad luck, but in my game the sun blocks felt rarer than any other one.
