Clicker Heroes

Just like Adventure Capitalist, Clicker Heroes is a free clicker game.
In Clicker Heroes you can make money by attacking enemy monsters. You can attack monsters by clicking on them or by buying Heroes. Heroes you have purchased also attack for you when you are offline.
Every 10th level you encounter a boss monster. Boss monsters have more hp and have to be killed within a certain amount of time.
