I have updated my game, you can check it out.
Doesnt really seem like it as you still have licensed cars in your preview images and the video 
.
You are also still selling the source for 3$ or more for what is more or less a tech demo.
If you want to get proper help i would suggest giving access to certain parts of the game so people willing to help, can actually help.
And you have to get rid off licensed makes and models!
Man if you want the source code for free just tell me privatly! I can help you.
You are asking us for help, and then asking us to pay for your source code for the privilege of helping you.
That is insane.
In the first time i was asking to help but someone asking me how your car game working with the car physics, then i give him the game link.Its just like that.
Iām assuming your first language isnāt English, so you misunderstood what people were saying. You havenāt provided enough code to help us debug your problem. No one cares about your code or wants to steal it.
