Hi, after few tries I've succeed to do 7 deliveries.
The game looks really good, you've used those assets really well.
The controls feels strange, the car is really hard to drive. I think it is because we move the on the car's space and not on the camera's space. I think it would have been easier if pressing left make the car go left on the camera.
Blue circles are hard to find and since we don't have a lot of time to find them it is frustrating. I think you could have make a blue dot indicator for those. Or increase the number of blue circles.
You should give a lot more bonus time. Or start with more time at the begining. The game feel really short because of that.
Next time try to put some sounds and a dummy music. It doesn't cost a lot of time and it feels great.
Sorry, I made a lot of critics but I think they could be usefull. Congratz on doing it with Love2d, I know that it is not an easy task. Good job overall.
PS: The windows links are not working. I had to find it in your github page here: https://github.com/SlimeBOOS/LD53/releases/tag/v1.0.0.
