To be honest I didn't know you could shoot until I came to the comments. I just thought the goal was to avoid the circles while driving, and I ended up getting them grouped up and drove at such an angle that they just followed me forever and assumed I won. Once I found the shoot button I died much more quickly. Some UI elements and motivation to shoot (maybe a score counter?) could help. The controls felt responsive and the looping mechanic was essentially seamless though, good work!
