The game would benefit quite a lot from a Full Scr.
It's a neat idea with a decent implementation of it. Visually it looks quite nice.
The gameplay is simple but engaging enough to where it doesn't feel boring and the audio is fine as well - the audio design could have been done better.
As for the car controls, They are okay. Not the greatest but fine for a jam game. For a top down shooter I usually expect a quick turning car, but this one felt too heavy at times to drive. Which for a time attack game, doesn't feel too good to be honest.
Apart from that the idea is decent enough and I would love to see where this game could go from here.
