It was pretty enjoyable
I've played a lot of defense games and I think this is one of the most difficult as it's simply hard to get starting. The ways the bugs move are pretty unpredictable. I guess with a little time and concentration I could be better at it. I will say that the designs of the bugs and the hazards are pretty creative. I just can't seem to tell where my health is and how much time I have left before I'm supposed to die. At least you were nice enough to include modes on which we can build up from.
