Is this what Jonathan Blow is trying to copy with Sinking Star?

Trying to copy is a bit harsh, but he has credited it as an inspiration for what's possible within the Sokoban format. I believe he was a playtester for SSR before it released, mid The Witness development.

Not sure, but Sinking Star it is an (authorized) amalgamation of pre-existing sokoban games so there's some relation there.

From this post by one of the original devs: https://bsky.app/profile/draknek.bsky.social/post/3m7qybidq7...

Perhaps a more direct relation: most of those preexisting games were made in puzzlescript, which (per the article) was also made by the author of Stephen’s Sausage Roll.

Blow originally did Order of Sinking Star as a quick side project. He thought that by using these pre-existing games as a starting point, he'd get it done quicker. But then he decided to experiment with the combinatorics of these mechanics that the game blew up so much in scope that the original starting point didn't help at all.

Oost does incorporate elements that were tried in a puzzlescript game “mirror isle” and sean t barret’s “promesst”. Dont think anything directly from this sausage one.

Copy, certainly not. But Blow was an enthusiastic promoter of the game when it came out and held it out as a standard of excellence in puzzle game design.
