Very Good.
This song I think is one of your better songs. The melody first off really drove the song forward and did not get stale after hearing it in the whole song. . That one synth you used (it comes up as the main many times, example is 1:40) was a very nice touch and it made the song edgy but not overpowering. Also there is what seems to be a xylophone that has been put through an effects box (not sure which one it is at this time) that comes up every once in a while that makes the song easier to listen too. The transition from the beginning part to the main portion of the song was very smooth and well done. The only thing I could say negative about the song is that the ending seemed to be a bit sudden, maybe a longer transition from that final chord to silence would make it sound a bit smoother and would in my personal opinion suit the song better than the ending you have now. Besides that, this song was made incredibly well and unlike most dance songs I have seen on newgrounds, doesn't get stale and boring after a few listens.
