Battle time
Heh, sounds like it would go well in a space type side scroller where you battle the final boss at this point. The tune is very well composed and sounds pretty much revved up and just being fired like a cannon of sorts as you race against time trying to beat the boss as quickly as possible.
The synth sounds really rapid and I like how when goes down it feels like another one picking up for it which is pretty neat to hear on this one. The starting air sound was nice too. The drums give a feeling of having to rush against time to complete the level as well. I like the aqua effect applied here as well.
Overall, not bad at all, does give a good feeling that you need to beat a boss.
