there's still a lot of options
The part at about 0:45-1:15 sounds lacking. How about another melody line with that?
The rest is great arrangement-wise. While the 8-bit boss stage sound is interesting, I think this song would be better if the samples for the guitz and beat were rougher, more boombastic. Somehow, DnB basses that growl like angry tigers come to mind as potential candidates to replace the distortion guit.
There's a lot of different options left for this song. Hopefully I'll be hearing newer version of this song in the future!
4/5 (I gave you a break because I respect the general idea)
