Pretty chill little puzzle game!
The simple but effective visuals with a great colorsceme makes the game standing out on its own.
The mechanics are simple and easy to understand. No big explanations or anything else is need, you can immediatly start the game. Not having any loading times is a big factor with keeping a great flow.
One of the biggest features i think how you implemented the audio. The game feels so alive my coming near the vistas in the game and hearing the ambient sounds.
Maybe controling the camera would be nice, especially walking torwards the camera is a bit tricky.
Your game is a great experience and something you can put on to relax. Great job!
