plays fine for me, just press play on top of the list.

sounds a bit messy to me, the mix is overcrowded in the bottom end, the kick gets lost in the mix, and the more synths you add, the muddier it all gets.

try taking away some of the lower frequencies from your synths.

as for the arrangement, its not bad, it all seems to get going a bit too early though, and then runs out of ideas
