Cool
It's very repetitive, as the person below said. You could add some more variation in rhythm at the beginning. The part at 0:41 is cool, with the different notes and all. I thought that was really cool ^.^ The part at 1:10 was also pretty cool. At 2:31 its a really cool part with all these awesome parts playing together. I suggest making the song shorter or get awesome earlier or else people would think this song is boring without even listening to the second half, which is amazing, especially at 3:25. >u<
The part at 4:48 is really REALLY cool. The tempo change at the end was a bit too random o.o
Overally: SO COOL at the end.
