Fantastic Contraption didn't try to copy Incredibots, and vice versa. Incredibots was probably being made and tested way before Fantastic Contraption game out anyway. They are just games.
I left it on for 2 days straight, and it still says my max time played in a session is 190 minutes, why is that? Also, to donate, it's based on every 5 times you get on the game and press the play button. (Refreshing pages works easily)
