Cute art and concept. I liked the music, very appropriate for the game. I'm not sure what the puzzles were though. I got all four stones to the end and everything bloomed, which seemed like the end. pushing the stones was way to slow, the pulling felt much better. I was also able to grab the stones from pretty far away (like 5 or 6 times farther than I'd expect), and might have glitched the stones over the bridges or the graphic disappears too quickly.
You mention further development of the concept in other comments. I think if you do so, more clarity on the puzzles will be helpful, and you don't need the areas to be so large when most of the space isn't needed. I wondered around for a bit, and it all looked nice but didn't need to be so big.
I concur with the different elements moving differently, either through different behavior after you push or different requirements to move. I think you could really invoke the elements that way. I think this is a good first project!
