Click green flag twice Mouse to select. Arrows keys to move around. Space bar to attack. For level 1-4, keep going right to get to the end. There will be enemies coming out, avoid or attack them. Don't go left...or else... For level 5, attack the only but strongest Xiongnu, defeat him to win. There are different kinds of enemies, you can find them in the Xiongnu index. However, you can't look at those you haven't encounter yet. You can also go to the shop and buy something.
