i only rate 5 if i'm amazed by the melody, so here ya go
i would actually love a remix of this melody :3

A good tune, but echoing what everyone else said: the intro is too long.
Otherwise, the rest of the tune is pretty good. Listening to it repeatedly, I find it a nice little tune to work to. Thanks for making this.

The first half is enjoyable in my opinion, and I'm not sure what the fuss is about.
I can indeed complain its lengthy, and it is, a repetitive beat, but it is an intro meant to be as you said, an atmospheric composition, used as an opening.
I believe cutting the intro in half would be silly, 10 seconds is a-lot better, since it takes about that long for it to loop its sound.
On the latter half... I'm amazed you created something so wonderful! It could be a part of its own chiptune dedicated to similar compositions if you went to expand upon it in a future submission. It indeed attracted much attention and popularity, I enjoy it too.
While writing this review the whole song looped over 5 times. Cause I absorbed quite a bit each time I went and typed a sentence.

The first half is too repetitive. Would be better if it was a little variation like a tone up or something.
Heard in Electric Brain-Spaghetti, fits very well.

yo just trim the intro and its perfect. its wayyy too long
