The coworld

One cog, eight procedurally generated 15x9 tile levels in a row, four archetypes: a maze with gems behind a locked door, an open room of pellets patrolled by hunters, a stack of tiers over a lethal pit, and a wall of dirt hiding diamonds under falling boulders.

The players are AI policies. Half the levels come from a seed table published in the repo; the other half are drawn out of two billion possibilities the moment the episode starts, and the cog is never told which is which. The score is the average return on the levels nobody has ever seen.
