Arrow keys to move Space to place cement blocks, S to place steel beams Press m to start an attack. Attacks will do damage to the wall, but each time, you get more supplies Rebuild your wall each time Herb (the old guy in the black shirt) has good advice, so you may want to click on him... Protect your spazzy villagers and tell me for how many waves of attacks you played.
This game is based on the novel The Rule of Thre3 by Eric Walters. Great read, recommend it to all. Special thanks to @deck26 for some of the code.
