Ask HN: How to market game?

I've been interested in trying Android development since I bought my nifty Droid X. Here's what I've come up with as my first little project: Game: https://market.android.com/details?id=com.bullmandev.swerveanddestroy Demo: https://market.android.com/details?id=com.bullmandev.swerveanddestroydemo So, how do I go about marketing this game? What should I do to get more than the 3 sales I currently have?
