Ok, looks like I'm done with this game. I logged on today and I had been reset back to 0. None of my perks...nothing.
Oh well. fun while it lasted. Looking forward to next one.
Found a bug. all the guns stopped shooting. The prices of some towers I had just sold didn't disappear, but the enemies kept moving...but when they got to my base; I didn't appear to lose any life. (I did eventually get a game over message though.)
Found a strange bug. My creature hit a monster and it went to negative hit points. It's currently slowly counting up to zero, but neither monster can do anything and they are both just sitting there on the screen.
Complete the campaign and play in paradox mode to remove the cap.
