You got a lot done within the amount of time you had. I am really glad you had the free-cam, as that let me check out the great level and buildings. It was great having the cars moving around! The downside is I don't think I got to experience all of the mechanics you had made!
Critique: First off, for me the sensitivity was much too high. I know its hard to have time in a jam, but not being able to adjust the sensitivity will impact a fair proportion of your players. On that note, I think I would have preferred inverted mouse controls too - but that is personal preference.
I found the camera was pretty close to the ball too, and unfortunately it was hard to gauge how hard I was going to hit the ball, or if it was going to go along the floor or in the air. Despite knowing there was a freecam camera, I also forgot about it for my first 5 shots, instead I was guessing where the flag would be (my mistake! but a reminder that players can forget something you told them on the title screen).
It was lovely to meet you lot, all the best in your game dev careers!
