Endless Tunnel by Btco

A simple arcade-style game where you have to fly down an endless tunnel avoiding obstacles and collecting bonuses. As you level up, the obstacles become more difficult and the ship flies faster.
Unlock achievements and compete with friends on the leaderboard! Integrated with Google Play Games.

This is an open-source sample available at:
http://github.com/playgameservices/android-samples

You can control the ship by dragging the screen (accelerometer is coming soon). Also, this game supports most joysticks and trackpads.

Note: this is my personal build of the sample, and there's nothing official about it in any capacity! I'm publishing it just for fun and to see if people can beat my high score :-D Also, it helps me find bugs in my code. So please report any crashes you get!
