Create an Android Game

I'm looking to create a simple Android racing game similar to Extreme Car Racing, which uses physics (box2d). It doesn't have to be the most complex game, but enough to meet the standards of most small-to-medium games around these days. A couple of things to note in regards to requirements: - Development in LibGDX and written in Java. - Must use sprites, collision detection, particles, UI, Audio, tile maps.
