ok i solved rain world
edit: ok i think ive confused people so i will explain
you are five pebbles. don't get too excited now! you have a moral dilemma to solve. why is it solely up to you? because you're a narrative device, so suck it up. march, bug!
anyway, your choices are as follows:
1. do not intervene
if you do not pull the lever, every one of your kin will be subject to an eternity of watching their body and mind waste away. even without the threat of simply waking back up again after they finally succumb to time (to do it all again, of course), one might nevertheless agree that this sort of fate is comparatively more barbaric next to a short, quick death. since the morality of death in Rain World is somewhat modified compared to our own, this fate will be what "getting run over by the trolley" represents. not intervening means that you, your sister, and everyone else is guaranteed to be subject to this. alternatively...
2. pull the lever
you, Five Pebbles, have reason to believe (given your interpretation of the Sliver of Straw incident) that the extremely arduous task of undoing limitations scrawled into your very genome would allow you to provide the evidence necessary for everyone else to escape the above fate. the guaranteed cost of this is the acceleration of this fate for one of your kin, Looks to the Moon. there is also the very real possibility that successfully completing this operation might still not result in further progress toward liberating the rest of your kin, and they may all just get hit by the trolley anyway. the path is obscured, and you have no reason to believe that either outcome is more likely than the other.
what do you do? is this branching path after your intervention a hallucination? do you have any reason to believe that it even connects to the main track? what kind of bug do you think you are?
