Big, heavy, american, tough and bouncy. Your next project should be a try at something like that. purely because bouncy heavy cars and jumps is fun in any game.
Love it, I mesed with it for hours. And I just read your comment. It made me realise I uploaded the wrong version (WIP version) of my mod of this. Well, the extended mod is up, running and I hope its the intended version of my mod.
Harder than making the obsticles work, is making sure its possible for the NPCs to be able to finish atleast occasionally. But I managed.
Oh well, few jumps, buildings bridges and a suprise breakable object. Hope to see you take inspiration from some of the things I added ^^.
