could use a bit o a tune up on the main chip melody, also the volume for some of the instruments are a bit off, weird usually there isn't a lot of bad things on your songs but hey everyone makes a mistake somewhere lol, this reminds me of a song from doom in some parts, also reminds me of sonic XD
anyway
all in all this would be a 3.5 to me
1. volume levels fixed
2. better melody on main chip synth
hope the rest of this when its finished will sound awesome,
hope my review helped
keep it up! ^ _ ^
