This was originally supposed to be a remix of a theme of the WebcomicRelief. When I made the remix I loved it so much that I ended turning it into an original work of mine a year later.
While remaking it I always noticed that the melody and rhythm sounded familiar to me but couldn't pin-point why... Until I remembered Doctor by Buzinkai. I don't know whether I came up with the name Lifeline before or after realising this, I'm just surprised it ended up turning out this way.
