theres a little cheat on the final lvl.if u run out of bullets and u hav 1 guy left to kill (witness) u can click on him and he dies.u might want to sort this out
retarded...i lost cause i typed in wat it said above a smoke ball ninja and it even shown 3 crosses above and it stayed alive and sent loads of ninjas and i died...
2 cheats that might help:
on falling blocks stay on the right hand side by the wall and you wont get hit
on disco disaster hold left or right then keep jumping and you shouldn't get hit
hope this helps copy and paste to keep goin.
