I wanted to give this game a 4, but it's far too random. A single piece of bad luck can waste all your hard work. The collision also seems to be wonky from time to time.
While I'm not among the people who are going to get all torqued up about an oblique reference to the 9-11 attacks, having Bush's plane crash into NYC is more than a little tacky. Combine that with a terrible game and we've got a 1/5.
"like a turd that just won't flush" My sentiments exactly. Levels take too long, I should be able to buy everything from the same screen, some of the wave groupings are just terrible and unfun. Please stop making games.
