Cool idea!
But the wall of text you have to get through to be able to understand what's going on is kind of frustrating. Also I managed to accidentally glitch my bugs inside of the shield barrier without destroying it.
Maybe you should add a health bar to the shield and the computers, it's hard to know if you're even doing damage because everything makes the same sound. Maybe also add some effect when a bug dies so it doesn't just disappear, and show on screen how many bugs you have used.
But it's a cool concept!
