Amazing job!
It's quite often we see killer re-mixes on Newgrounds, but it's not so often that they come in at this incredible caliber. Truly a job well done.
The entire song sounded synthesized, but considering the nature of the song (being from a video game), it fits perfectly. The transitions were all rather quiet and they were hard to notice -- a good thing if you ask me. You made them truly invisible, but I didn't care because it still transitioned so well.
At about 2:17, I enjoyed when the quieter nature of the song took over... and I loved everything else too... this is just a fantastic song that goes on for so long, and I loved every moment of it!
This is one of my favorite songs on this site, and all I can say is: wow. Thank you for making this -- it's truly great.
