Hey!
The visuals in the game are pretty good!
The sound does get a bit repetitive but it's ok.
My main issue is that the game lacks goals.
Right now there is no motivation to replay the track.
you should at least add a timer and a highscore to each track,
so that you have motivation to improve and get a better time!
Online leaderboards might also be a nice thing, but that's a bit harder to do.
I think if you work on the gameplay features some more this could be a nice little racing game!
