I unpacked the whole zip into a new and empty directory and I cant run the game sorry.
Tell me if you know how can I open it or if you push a fix, I will try again.
"can't find libmcfgthread-1.dll"
It's working ! there's still a few crashes but I can play, and I see what you tried to do I think, the different vehicles and the terrain it changes the way you drive around with a score or obstacles maybe both it would be very fun, I really like the Idea, If you ever find more time to finish it I would like to give it another. Good luck !
