Thanks. Stay close to the WIP! One tip, don't use instances, use pre-pooling of the meshes, or there will be lag while playing.
Another Update with skidding mechanics for underpasses. Worked on the running animation a bit. Little fog added. Key bindings are changed too.
Now only arrow keys are used for left, right, jump and skid.
