A bit repetitive, you could have just shortened it to around 2 minutes to be honest.
And if you are going to string it out for a long time, try making each loop a little different, add or remove instruments, change the notes a little, doesn't have to be much, just to let the listener know it's not exactly the same again.
And I'm a hypocrite since my songs are just the same thing repeated over with a bunch of shit added in.
Thanks for the review Poonpun!
I agree that it is a bit repetitive, although it is meant to be that way. I've created the song for people to use for their arcade/retro/8-bit games and a lot of them contain short, looped songs.
I made the song 'round 5 minutes so people would be able to cut something off if needed.
I could've extended the song a bit with a couple of more changed sections though.
