Fun, simple and original puzzle game. I found it very easy to pick up.
Music is cool, especially since you composed it yourself.
For improvements, I'd say work on the graphics some more. It would be nice if the place where the three tiles are placed at the top of the screen had its own border/background. Sometimes when I went to place tiles back, it would take a couple of clicks to put them back down.
I enjoyed playing your submission. My lowest score was 7 with a Complete Garden.
Well done!
