It really Awesome! But I feel like it not so loop-able. For a three hours, this is one hell of a song! XD
You snagged me with that 8-bit nostalgia, nice work.
pretty original, the second part is not expected at all and make the song non repetitive, may be the loop is kinda too much "harsh"
Please contact me if you would like to use this in a project. We can discuss the details.
