Catch as many thieves as you can until the time runs out - it is a simple as tapping the person who has stolen the colored gem!
For every criminal you catch, you can extend the time - but, be careful, you lose time if you tap a non-criminal.
Challenge your friends as your score gets added to a leaderboard on GameCenter.
Made it slightly easier - based on feedback:
* Gem is bigger.
* Gem flashes every few seconds.
Challenge friends and check leaderboards and achievements.
