update says there are two logical points where he could end the next chapter, and that depending which one he decides to go for, it'll change the release date. so it sounds like he's debating between a smaller, faster update vs a larger, slower update. the image is just stock image of three hands playing rock paper scissors, not anything from the game. it could be a clue, or not!
i would appreciate weekly patreon updates from the dev, and i think it would be good marketing for him to do more communicating. he has a lot of excited fans, more updates on development would give more people reason to subscribe to the patreon.
