Very cool entry, I like the visuals a lot!
Animations, cutscenes, the backdrop, cars... really nice work.
What would benefit from a bit more love, is managing difficulty. It's hard to get a into the game, because the first runs end quite quickly, and the downtime is long (it takes 18 seconds till you can be back on the road). Landing on a roof of a car feels like it shouldn't result in game over. The left side ramps are significantly harder to hit due to incoming traffic.
Another one is controls. Strafe at slow speed is nowhere near fast enough to handle incoming traffic, and at fast speeds there is no time to react to it. The launch itself feel unpredictable, either launching you too fast, providing barely any increase in speed, or anywhere in between. And given how much your ability to move laterally depends on your speed, trying to launch yourself between two vehicles results in failure more often than not.
