Quite good, a very nice build-up with the beats and melodies. At 01:50 the nice synth really adds a lot to this song, also a bit of a different melody. I think that it all just fits together very well.
The main synth which fades out around 03:24 is however repeating the same melody a lot, could have some more variety in it in some way.
Hmm, I should look up this genre synthwave, didnt know that it was so good.
Not a bad song, 4/5.
