Nice little concept! it would have been nice to see the times you have finished each track maybe on the menu so you can see what time to beat for your next race. Not sure how hard it would be to add a ghost version of your self so you can see how well you did last round or how bad your doing in the current race.
upgrades would be nice to make it so it was a bit easier to get around corners.
Is the car suppose to be like those F-Zero ships? otherwise making it more look like a car and which way is forward would be huge QOL
definitely something you could build off of!
