Nice intro scene and nice city environment. You did a great job with all of the models of the city, other drivers, and the passengers.
I found the starting point of the player was wonky for me. I started with my head above the car roof but later switched to the proper height mid game. Not sure how.
I think it may have just been my driving style but I found my wheel swerving all the way to the right a lot when I was trying to turn left. Then again, I was always trying to gun it at full speed but it did feel like I lost control over the wheel direction for a bit.
Amazed you did this within a week! Great job!.
