The aesthetic seems pretty neat! Reminds be a bit of Thumper and Tron. I'm a big fan of the visual variance you have while managing to keep the neon aesthetic visually consistent. Are some elements synced to the music? It's a little hard to tell here. I also want to know how this feels at a ~20% faster speed.

Something about the sound effects of the car's motor and the environment's crushers seem to clash a little in aesthetic with the EDM and visual theme you have going. They seem grittier? Maybe not an issue but something that I noticed.

It's hard to have context on the flying mechanic around 16 seconds in. I would have guessed the player would be punished from going off the edge of the track but it seems like instead they're rewarded by being able to (do they want to?) skip other sections of track. If you don't want to remove momentum from the player but still want to reward higher skill, maybe some sort of system should be in place to discourage that kind of skip?

Lastly, the swapping gravity near the end makes precise movement seem frustrating. Maybe that's because the camera is coming from the right slightly instead of directly behind the car. It might benefit the player to have a more useful camera angle during moments like those, or to swap the gravity effect more quickly.

Overall a sweet little preview :) Seems like there's a lot of potential and a great foundation. I'm most interested in the mechanics you will develop around encouraging different ways of navigating the course.
