Fantastic aesthetic! I think the puzzles were great and the mechanic of trying to match the breathing with the different objects in the environment was really unique. I had to cheat though, I was stressing myself out trying to breathe with the character and not sure how fast I should be breathing out (especially the car in the background! Long long breathe out! Perhaps something visually colorwise or some kind of vignette to indicate how slowly or quickly I should be breathing out to time myself with the character. Fantastic job all around!
