I like most of the melodies and instruments, but there are some points I didnt like.
I didnt like the siren-y sound in the background, the bass (I think) at 1:30 and the part at 3:40 didnt sound like it belongs to the song because of the instruments.
I still like this song, as I said the melodies were really good, liked the chiptune (I think) sounds and the transitions were really good too. I hope this helps. Keep up the great work!
P.S.: The (I think)s just mean that im not sure if it really is what I think it is.
