The song is simple and repetitive, but in this case, these are good attributes. I was very relaxed while listening to the song and the main melody stayed in my mind for minutes after my first listen. The sound design is excellent; each synth has a unique sound, and in my mind, a unique color. The dominant color of the song changed between navy, magenta, and bright green and yellow. The vocals make the transitions seamless. I like that you kept the song at an appropriate volume instead of compressing it. My only criticism is that you could have made the piano introduction more interesting instead of playing plain chords.
