PaperCraft

Grab your Android Wear watch and take on a never ending onslaught of little paper bad guys. Swipe and tap to clear out everything and rack up points. Challenge your friends and the world on Google Play Leaderboards or just try to find all of the achievements. PaperCraft is a mini space battle without getting your phone out of your pocket.

PaperCraft is an Android Experiment and that means it's open source.
