I'll not finish the entire map, but just finish Portland, there are a lot of unfinished areas in my demake.
I now have a bit more experience with car physics thanks to other side projects. I think the main things I need to do is lower the center of gravity with a few tweaks on the car's acceleration, and make the wheels less slippery.
I think when I'll have a bit more free time I'll fix everything and finish the map in a big update, to at least have a fun and playable demake.
