It wasn't the wimpy play preflop that did you in. Even if you had made a strong bet there is a good chance that you get called by the AcTc anyway, play is pretty loose in a freeroll tourney and honestly thats where you get your best chance at picking up chips, getting the AT suited to call your AQ when Axx lands on the flop. What it might have done tho is made your opponent think about folding on the flop IF you had made a strong bet preflop. But instead you chose to min raise and give him every reason to put you as weak and raise you all in.

Your mistake IMO was not letting the hand go on the flop. You took a chance and saw a board, you made a stab at taking the pot once you whiffed and the board failed to hit you (albeit a very weak stab), and you should have folded your no hand/no draw when he reraised you all in.
