This game has a very weird sense of humor...
I was playing survival and there were 7 or 8 ninja on the screen and all but one ninja's name were the same. The lone ninja's name was "pimp" and the rest were "sexy".
press p a bunch of times really fast... a box in the pause screen will pop up, it have a text box and a button... It's a cheat box and with a specific code you will get a insane amount of money (in the trillions), search it on google and you will find it. a bunch of phillipeans found it... good luck!
HINT: on lvl 34 the picture it show is actually a solution IF... If the green backwards L is put a milimeter (very very small amount) to the left... either way, if you do that what the example that tells you not to do, it will actually work because your's will not be exactly like theirs... either way, if you do that what the example that tells you not to do, it will actually work because your's will not be exactly like theirs...
