This is what the game is saying: Buy this, pay us that. Want weapons?..oh you need karma..want karma?, pay us, want to level up? you need karma..want more karma? PAY US!! screw.you Broken Bulb. You greedy pricks. And why am I loosing every battle? I even loose to people lower levels than me. I have the best possible weapons I can have at this level..and since you have to choose between buying weapons (which are expensive anyways) or leveling up...just..agh. They made it look like a flash game..but made it so you have to use Karma for EVERYTHING. How do you get karma? PAY US!!
Easy way to get the medium badge if you hate this game as well. All you do is keep pumping your karma into one or two ninjas. When you go to select a group to fight, scroll down to the bottom. There will be some groups that are created by the game. Select the group with the largest army as your group should kill most of them in one shot and not take much damage. To make things go quickly, as soon as the fight starts, click skip up on the top-middle of the screen. The money you make from this will pay for your hospital fees after every fight and you should start getting a large amount of excess money. When you fight a group for the 5th time, they will be unselectable for about 10 minutes. Just choose the next army on the list with the biggest army or go back a level by clicking weaker on the bottom left of the screen where you choose where you are going to fight. I did this and I got my medium badge within about an hour of playing.
If you lose a tournament, and start the same one again, you face the same person again, ever notice that? stupid, until you level up its a different guy
