Some things i want to notice:
- It seems that general gameplay works which is great
- Car physics as already mentioned are well, like glue on the ground
- Please increase distance of sight (and optimize some of those particle effects)
- Use higher resolution car models, 8 edge tires are really out of date.
- The level seems to be built in WED. If yes, then activate shadow maps, the game looks weird without any lighting at all.
- Overall use higher quality assets. There are a lot of them out there. (The skycube is outdated since it came out ;))
