As you already know there are few versions of the stick war published till this time, but personally my favorite one is the first version, that you will be able to play right now. You should try your best to reach the final point in every level to kill the boss. It will not be as easy as you think but once mastering some of the tactics of the game, you will surely develop all the essential skills, that you might need. Also you will be able to upgrade all the characters that you control so make wise decisions to create the team which has all the abilities that are indeed for winning.
