Apparently abandoned by the developer...

A lot of fun, for what it is-if you liked Desert Bus, you should like this. Its a little harder, as the road is narrower, but thats not wholly a bad thing. The only catch is, the CB radio and other frills wont work- instead youll get a message saying "There was an error posting the check in", and this will prevent you from being able to unlock upgrades. Other than that, all good. Nice to have a game that doesnt take your full attention, to play in the background while you do other stuff.
