What a wonderful idea! I feel that there is room for improvement, but since I consider the mod a hair over 4 stars it seemed best to round up. ;-) I'd consider this a must-try mod for almost everyone! I'll share more of my thoughts in the discussion thread.
This is the best idea for BNG and well planned out, as usual. All but the metal boxes were very challenging and a grind. I suggest doing oil filled berrels and a giant gorilla at the top, for atmosphere. I had it working with the last version but no success with the teleport fix update.
Even though my computer was running a few of the challenges at 10 fps I still had a blast, and will continue having a great time testing what cars can make it. With this system of teleporting I can see people making some cool events. Game/Simulator is getting to a very interesting stage of development!
This is a lot of fun. It runs well enough on my system, though the hill could use a little tuning so that objects don't always end up off the track, as it becomes much too easy the longer you are on the track.
