Your menu will be pimped out with this music. It's got that sort of simple anxiety feeling to it.
The only thing that caught my attention: The guitar-like pluck instrument was off-beat sometimes. Did you record that on a midi device? If you, you might want to consider quantizing it or programming it by hand to make sure it's top-notch quality for your game.
Other than that, great song! Almost reminds me of Final Fantasy... VII I think.
