Beyond Development: iOS app after approval of Apple

Yesterday, my app is approved by Apple for App Store and I released it to the public. The upcoming, bigger problem of this is how to make as much people as possible to know and use the app, in my case, play the game. I know that my game is a good game because all my friends and classmates loved it during development (it was a school project) but now we need to get it known to more people, and make the words spread.

This problem is should not be a concern for a programmer, but as a solo developer or a small team, I have to take the job of the product manager as well, trying to promote the app.

I am not sure of how to promote my game. If you know, please comment and tell me.

The game is here:
