I just played The Witness for the first time last week, so some of the references in this were still fresh in my memory, which made this game particularly interesting. Being able to rearrange the island itself, and so many things on the island that I assumed was just scenery at first, was really cool. This has an impressive number of unique puzzles for a jam game. And tbh I think I'm now convinced that sliding blocks lend themselves better to Witness-type puzzles than The Witness's mazes do.
