What's all the fuss about?
Everyone complaing needs a heavy dose of "man the hell up." This game isn't as bad as you think. Yes, the part retrieval is a little too random at times, but I honestly had no difficulty completing this entire game because I decided to use that lump three feet above my ass, as opposed to expecting the game's creator to hand me everything.
That being said, at times it was a little repetative, and like I said, you need to find a more organized way to disperse new parts. It shouldn't be immopissable to get a rocket launcher halfway through the game. But I liked the theme, that was pretty original, and I liked the variety of towers. You need to boost the damage given by the magnet though, otherwise there's no point in even having it.
All in all, a great time waster for when you're bored at work. Well done!
