At a glance, this looks like a Gemcraft copy. Then you notice that there's actually incentive to pay attention to tower abilities, as opposed to just trying to make really powerful pure gems. Then you realize there's only a couple towers worth using. Then it feels like Gemcraft. Yep. Not all bad, though, and if it weren't for having Gemcraft to compare it to... 3/5. Now add a mute button.
Amazing idea executed poorly. I was sitting still when I let someone go and they shot almost straight up away from my nest. Aside from the unpredictable angles you sometimes get, it was still a fairly easy badge.
