so since none of the alpha kids have a time or space aspect, had jade and dave not lived through the scratch the alpha kids wouldve been immediately doomed right? well werent, technically, by the games standards, all the beta kids expected to die? had jade not pulled her 4th wall stunt they would have, so the scratched session would have failed? why would the game create a scratch it knew would fail if the kids didnt cheat the system?

Because it knew the kids would cheat the system.
