2D Endless Runner Game

I’m new to unity and I want to work on an endless runner game, and have a few questions.

  • Is it better to have one really long scene the loops or many scenes with a script the randomly picks the next scene.
  • Is it possible to create multiple unity scenes in a game and have a script pick the next scene?
  • Will the random scenes work okay for an endless runner game, or will it pause between scenes?

Thanks
David.
