I would love if there was a "build your own map"-function. Placing out the route where the enemy move; how many waves you encounter and what kind of enemies; where and what kind of towers can be built etc etc. And also a test play for the customized map before saving at as a complete map.
Was just fighting a "Gory Rock".
What is the appearence of it? Does it bleed or is it just a flesh-covered stone? A heap of meat? Is there a bone stuck in it? Are rocks living creatures? Was it in pain? Agony? Was it dying or already dead, or maybe risen from the dead?
Don't tell me that I have to feel sorry for stones also.
There should be more awards, like "you shit so hard you flew to the moon"(type "fart loudly" or something) and "sometimes bodily functions never cease to amaze us"(type "pee" or "puke" etc).
