How to Make a Puzzle Game Work?

Something that i'm trying to do my gan is that from the startpoint, everything is somehow, like, connected. It's not like you switch to a different screen, or like, you know, i wantit to be at transition,. So that's something that i just to make it a bit more interesting. I feel like there's feeling, there's a lot of it in there already. But yem just, i'm so curious, did you build this in parallel to the puzzle game, or was that something you did later, or, i don't know, i'm just curious about what your process was.
