I can tell that this is the same game that Brackeys made tutorial on lmaoo it's just different assets and more done

I Think its fine but my game froze up and I lost my progress and its doing it every time now so dude do a better job and please try to update it a little like add skins you can equip and make it so you don't have to press controls to play and make the menu more exciting *JUST A SUGGESTION!!!*

The game is really easy and needs to be more difficult, winning or losing should be determined by how much damage you take instead of if you touch something. sometimes it becomes unresponsive.(sorry if it sounded rude, good luck) :)

I think the basic idea is pretty good, but not original:
There have been road racing games for a long time. (40 years?)
You can maybe look at some of the other games, and see what they have done to make them quality games.

Better graphics is an obvious one, and that includes things like a HUD.
(Heads up display, to get you know your speed, RPMs, what gear you're in. Etc.)

The current system here is just flat out acceleration,which the player has no control over.
Most of these games have some sort of accelerator, if not also a break.

(Breaking an F1 car can slow you down at more than 1 G without even touching the break pedal, just from air resistance at high speed.)

While you've done a good job implementing the day/night cycle: the lights of the vehicle in front of you is not very good, and you kind of need to know it is there to avoid it.

I tried playing this in full screen, and after winning the 4th race: the game hangs, and eventually I get an error to stop the page or allow?

Refreshing resulted in the same error after the 4th race again.

If I waited for the 5th race to start: the game would start as I'm smacking into the car on the 5th race.

I find that the levels are easy and short, but otherwise I like the cubic graphics.
