A sad story where you are in control of slowing down or speeding up 'KIDS', following or running counter to conventional wisdom. You learn how not only does ethics change with group size, your actions feel ethically responsible or irresponsible depending on group size, and the same decision is impossible to make when many 'KIDS' depend on it.
A pretty direct description of how I saw the interactions:
On the individual level, you care about the one you push around. You speed them up and question if they shouldn't have been left alone to fall at their own pace. They stand around holes and you push them in, making you want them to find other holes. You push one through a challenging thing (school?) and wonder if it isn't going too fast for them. Then they fall face-down on the level below (which again has holes).
One the group level, the opposite philosophy takes hold of you. If you don't speed all of them up, you feel bad for letting some remain slow - the level only continues if all have been treated the same by you. Groups get in disagreement about which way to go, and you need to convince all of them to go one way, and you ask if it's the right way. Groups run through the level and find holes, either following the leader down the hole or following them away from it - you can choose who goes down, or it seems so, but the remaining runners are stuck running in a loop. You feel bad letting the others waste time, so you send them all down.
Having sent thousands of 'KIDS' down the same hole, one of them regains consciousness and swims upstream, gathering a few followers. But after a while they all fall down the stream again, being met by the big group and seen as outsider until they jump down the next hole. The group is then lead by a few who are in disagreement again and you can reach agreement, but then a single one disagrees and you can only continue by telling him to agree, against your previous gut feeling. Then you push everyone in the agreed-upon direction.
