I find funny the concept of not being able to control the trajectory of the car. You can see death comming your way and you can do absolutely nothing to avoid it. I guess this perfectly answer the theme of the jam !
That said, I think this is also frustrating for the player (please let us shoot forward!).
Frustration is not really a felling you want your player to feel, especially in a context of a jam, when we have mountains of other games to rate and quiting to move on at any frustration is reaaaallly easy for any of us.
The game has some issues regarding lisibility that could be an easy fix.
To make it better you should think of changing the color of the enemies so that they don't blend like that in the background. You can also give them a contrasting outilne.
You should think about the camera. Maybe the car shouldn't be in the center of the screen, but closer to its bottom so that the player could see the enemies arrive.
Regarding the design of the game itself, you really removed the player's control. Next time you want to do something like that, maybe try to think about how to give the player the illusion of loosing control without making the game too frustrating.
