Thanks a lot for this review ! We are so happy that the execution of our idea and the art style appeals so much !
To answer you question, there wasn't that much more about it, because we just directly implemented the fact that you can revert the state of contraption (we can see them as levers), then the 2 puzzles were made with simple use of those contraptions. I was thinking "Let's make those 2 and think later about more usage of the stitch back" but... We took a lot of time to make the whole thing coherent xD (adding the map, the dialogues, putting the assets together), and little did we know that we didn't have time to create more puzzles
So yea, the mechanic is here, but it's not currently used x3
