fifty levels
there are fifty levels of increasing difficulty and my only suggestion is save up for the shotgun make it perfect and then save for the fulp gun if you do that you automatically win if you try at all
the fulp gun as a rapid fire shotgun that shoots rocket launcher bullets which cause splash damage if you try and have the fulp gun you cant possibly lose
There is also a secret password that if you type in you get 500,000 money at any given time i've written it down in this review but you'll jusst have to find out which word it is
Happy hanukah
