This Twine game, written in 500 words or less for the Neo Twiny Jam, is about Sisyphus.
I've seen a lot of revisionist takes on Sisyphus recently, but this one is a straight-up thoughtful interpretation of the original myth as-is.
The short 500 words get reused a ton as you go through many very similar loops. There is a gradual increase in knowledge, the loops changing.
I found that very effective. But the frequent use of yellow-on-white was a bit hard to read, and it got repetitive (which I know is the point, but an accurate representation of a frustrating thing is still frustrating).
