ellywyn :"Having an endless click-option takes the challenge away in this game, because you are sure that you will always win no matter what. It is fun to set people on fire to get rid of frustration, but a little more challenge would just be.... nice. 3/5 with a potential of 4/5 if there is a max clicks installed."
You know, the challenge mode has a required score to pass the level so the restricted clicks would be useless...just saying.
