A great start.
The gameplay is solid, and i had fun playing it.
Getting more points for collecting the small green dots adds plenty of depth when the player has to decide if they want to:
a-Drive at max speed ignoring the dots preventing the time from decreasing.
b-Drive slow attempting to preserve your lives and collect the green dots
having to make this choice every time you encounter a checkpoint is excellent for player engagement and depth.

The controls do not really match up with the direction the car is moving.
I would recommend rethinking the control scheme.

Add in a difficulty curve and with a little refinement you have a pretty solid endless driving game.

Great job.

The controls are a bit weird, but still alright to use. I think it would be best to them go by what we see on the screen - so switching the keys would have made this better (UP to turn left, DOWN to turn right, LEFT to slow down, RIGHT to speed up). The game could also use a better appearance as well with some sound effects.

Overall, not too bad of a concept, and I think it has potential.
