A horde of stick-figures storms your wall, grab them straight out of the air and hurl them off the screen before they tear the castle down.
Each wave sends grunts, brutes, bombers and ladder-carriers marching at your keep. Pinch an attacker, drag him around, and release with a flick to throw him off-screen or smash him into the dirt. When throwing isn't enough, work the catapult to lob a boulder into a packed crowd. Clear all ten waves before your castle's health hits zero.
Gatewall draws on the flick-defence games that were common on the early web, where the input was a drag rather than a button and the physics did the rest. The form was widespread and largely anonymous, so no single title is claimed here.
You defend a wall by grabbing attackers and throwing them away from it, which means your weapon is also a way of making things worse: a badly aimed fling puts an attacker back into the crowd, and a well-aimed one takes several with it. Because grabbing takes as long as the drag does, the cost of dealing with one threat is always measured in the ones you were not watching.
Gatewall is an original, free browser game that turns siege defense into a hands-on physics toy: instead of firing on the enemy, you pick them up and throw them. No install or sign-up required.
