This game has so much potential in it's best moments it's already very fun so good job :)
Here's some critic:
The Steering is very confusing by just moving the left trigger different things can happen 1. the car beginns to drift 2. The car steers slightly but not enough so you end up driving in a tree 3. The car actually does a normal turn. It's a normal thing that the car reacts differently to different circumstances but in my experience it happened very unexpected and i didn't feel in control of the car
Same thing for rolling the car left or right and drifting. When Drifting I also noticed that the car sometimes stops to steer completely.
The tracks are build interesting but often the streets are very thin especially with controlls like these they can get very frustrating. Also at some points I was slightly confused at first where to go. Maybe at critical points there could be signs with arrows.
The overall graphics are ok the cell shading is a good idea and I like the concept of most levels (gameplaywise and visually) right now it's a bit barebones but It's probably not a priority at this stage of development. In fuure it would be awesome if you experimented with different foliage and lighting effects :).
The menu navigation is a bit weird with a controller right now some things can only be done with mouse and keybord. Also it would be great if the "back" option could always be triggered with the b button (on xbox)
I hope I wasn't unfriendly with all my critique overall I am really looking forward to how this game progresses
