Talk about stupid. I had a gangrape of a maze going on in MEDIUM difficulty and I was doing real well (If I asked myself). Then a bunch slipped out and went for the end. I went to buy the Stick Man, but the damned turret was selected and I couldn't de-select. So I basically watched in awe as I saw them, one by one, go into the exit. I got SO pissed off, I had to type in a comment...
Anyway, it's a great game. 10/10, 5/5, you get the idea.
