No, there aren't any invisible towers. What sometimes happens is people turn into a tower without seeing it. Make sure you dont turn untill your entire space ship has passed it. dont forget that your ship is about 30 meters long.
No, I don't like Juze. He gives all of my games a 1/5 and then puts out something this crapy. There simply isn't a rating low enough to describe this shit.
I don't think you guys relize how hard it is to make one of these games, so until you make a flash game that's better, stop complaining. And for the record, it took me alot more than 30 minutes to make this.
