That's a very impressive work done in such a short time. Amount of features and details is incredible. Audio is perfect, I wouldnt change a damn.  Solid basics of good graphics there as well. In terms of simulation I had a problem understanind what is going on for first couple minutes. I'd love to see some elemnts better explained (but it's amazing that you managed to get pretty much everything commented with explanation in such a short amount of time). In terms of fun, I guess it's not my cup of tea.  Overall, amazing job. Your production efficiency must be on Amazon level :D
