great but
It was a great tower defence game in my onions* but after a while, maybe after level 20 or so, I think, the enemies become too hard to beat and you have to go chase them down every time, and the towers are too hard to upgrade enough to kill them. And then after about level 40 it is literally impossible to kill all the enemies in each wave unless you use a powerup, and they are rare especially at that stage. And the towers barely do any damage either, just like the hero. And the bosses you might as well not even try to kill after 40 because even if you keep EMP'ing them and stunning them they barely take any damage. But it is a good game until it gets too hard. 8/10 is what you get for the part where it is not impossible, but It gets too hard too quick so 6/10 is my final score.
