Good or bad fold?

Cardschat Bronze Freeroll. It's the second hand of the tournament, so everybody has around 200 BBs.
I'm in the cutoff with Ac Js.

He shoves, I fold.

Would you have folded here? Keep in mind, it's a Bronze freeroll, so villain may be a beginner (also because he limped). Anything else I could have done better?

I think it is unnecessary to get involved like that just being the second hand of the tournament and having no information from the villain.
I would make the first call but I think I would fold on the turn, his line is totally weird, limps, calls a raise pre-flop and donk betting on the flop.
As I said, without more information from the villain, you can't have any idea what kind of hand he does this with.
I make a note of it and give up.

weird spot, he could be having worse Ace, or any random staff
I would call personally, but you never know
