Oh my goodness! Everything about the song brought me in! The sounds at thirty were cool, though, a little anticlimactic. I think the chord progression fits really well with that arp-thing you've got. I like 1:30 where it takes on a darker flavor, because that's kinda what I expected earlier from the intro. :P
I think your melody was cool and you should have had more with more variation.
Overall, I think this is very original and well done. Maybe add more bass? that might just be me or my headphones.
Well done! :D:D
