with the right know how it is realy easy to get far, on my ipod i got to wave 110 before i got bored [i took a pic when it was paused and i had 500k+ cash and full lives, on the ipod you cant buy them premium upgrades like double cash either] i started the level from rank one i quit the game afterwards tho cause of a little bit of lag and tbh it took over 5 mins each wave so i got bored : /
