In Hill Climb Racing, your progress is limited by a few factors: crashing, running out of fuel and reaching unclimbable obstacles. However, after playing the game for some time, I have still seen no indication of any level actually "ending".
Are they procedurally generated and go on forever, or are they just hand crafted to such a distance that nobody can reach the end in practice? Maybe a combination?
This question may have been asked before, but the accepted answer interpreted that question as one about game progression rather than level length, and the accept kind of "closed" that one.
Now, I am aware that the practical answer would be likely to be "It doesn't matter if they end, you can't get to that point anyway", but I would still like to know (it may require some official source).
