Pillage the Village is the spiritual sequel / literal prequel to Defend the Castle. The story explains why your antagonists in DtC are angry with you in the first place… apparently you went around throwing people into the air and slamming them into the ground, occasionally crushing them with their own houses and casting wicked spells on them.
And that’s how the game plays, basically. Prevent the villagers from escaping to the left and right sides of the screen by hurting them mercilessly with simple physics. In between rounds, you can buy magic spells with your dirty blood money. It’s fun, it’s simple, it’s relatively inventive. And the game does a good job of introducing new villager types to make your life harder (God how I hate those dopes with the parachutes).
Beware some of the technical issues, though. Occasional ads displayed between levels can cause the game to hang if you have Firefox with Adblock, or Safari. The game will also churn on slower computers. Look out! (XGen Studios has since contacted me to tell me that they have since fixed these problems.)
By the way, Jay is Games (source) describes this game as “a smashmortion of click-tastic mayhem!” (Snicker, he said smashmortion.)
