Bob wanted to escape

Can you make it out? A short racing game set in a retro sci-fi dystopian landscape. Ride against time, collect orbs for extra seconds, dont hit the walls, find the exit. Simple as that. This is a first game I have finished in Unity3d based on provided free assets. A lot of the stuff was crafted in 3dsMax, including track. Still a beginner in coding and gamedev, I would appreciate any feedback and critisicm from you guys on what to polish, fix and update.
