Just completed it, first 10 levels are impossible to get through without losing lives, needs more waves, I never even got to build the final weapon. lasers seemed powerful enough once at level 6
will keep an eye on it, hopefully we'll get a difficulty setting, extra weapons and a lot lot more waves... the game allows for so many weapon placements but I completed it with only 10. 3/5 potential for more.
4,094,821 FT with 60 nukes, could have been more but I just forced a win. 3/5 the ceiling sucked and when traveling at max speed pick ups dont register
