It starts on the map; the only level is Tolarian Fortress. Click on the castle icon to start the level. Press C to collect gold in the mines when the miner shows up. There's a coin symbol next to each warrior; that represents how much it costs. When you get enough coins buy troops on the top of the screen. The archer doesn't kill yet, but the warrior does. The arrow on the left of the screen shows which row the units are sent out. The castle with the heart shows your life, and the coin shows your money. Stop the zombies from killing your castle. Check back after a day or two for another update! Currently this game is fully made. There's no story yet, but there is a money system, enemy system, and a unit system (recruiting troops for battle).
