If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
This game is very addictive, very simple, and very fun. The basic idea is clicking stick men and throwing them up in the air to let gravity do the rest. If you can't keep up with the enemy your castle will go down. I highly recommend this one.
