286 M gems later, and there is no real benefit to it.
I wish there would be more benefits to having the gems.
The game is absolutely fantastic otherwise!
It's the same thing as the previous ones, really. And the "different routes" are just a bunch of holes. At least go out of your routine, and add more content like a 4th and 5th car - or the opportunity to finish a level by not (almost) maxing out everything.
I think both! IWBTG players made that game!
