This game is definitely very well done. It is a classic shoot them up like Blasteroids, with nice physics and effects. There is a breathing mechanic to attracts power ups to you, and a breath out mechanic to use the same power ups as projectiles against the enemies, which is quite a neat idea. But personally it feels like everything is so relaxing, the music, the sound of the rain, the water effects that I don't feel I need to calm down or chill at all. Maybe more enemies or faster enemies would have give me the adrenaline and then, in between levels, the relaxing music would have made me calm down. So I think the game need some stronger contrast between action and relaxation to hit that spot.
