At the beginning of the game I felt a bit lost, I missed the stone with the lights the first time and it took me a while to find what I needed to do, later I got stuck again when I got to the plants that makes different sounds when I interact with them, maybe you should work a bit more on the learning curve, it can get a bit frustrating if people doesn't know what to do next

The pros:

The game is beautiful and the music is really relaxing, I like those kind of puzzles so I think you just need to polish the gameplay a bit more
