Thank you for writing! I appreciate you engaging with the design ideas here. I sort of got distracted with other stuff and stuck again, so I haven't thought much about the design of this project (although the story and themes are always on my mind).
I agree with you in that it'd be nice if a significant part of the game is the 'engagement with the world'... I wonder how to balance that. In my experience I've personally had a hard time in balancing games with two big 'systems' (in this case, mapping and exploration). Either one gets cut or they end up existing a bit independently (e.g. Sephonie's Linking/Platforming) But maybe it's a challenge worth approaching.
It's frustrating to not have many game reference points to go on. The closest thing to the 'trial and error' I can think of is Mu Cartographer - really interesting game, basically it's a procedural world you navigate by twisting strange knobs, and you can find treasure in the noise. https://store.steampowered.com/app/513360/Mu_Cartographer/ Of course, that game is pretty different in design goals from what I have in mind, but it feels like somewhat of a proof of concept that 'experimental exploration' could be fruitful.
Real life has a lot of great analogies with the game, now that I think about it - often google maps is just 90% and the rest is having to improvise based on street/outside conditions, street signs. Paths to a place are full of things that you didn't expect, pleasant surprises... hm.
The idea about having 'partial undo' items is really good, it definitely feels important for the exploration to be open to experimentation, rather than punishing for failure. Sort of like how Mu Cartographer lets you know when you're kinda close to a treasure, and you can keep unadjusting/adjusting knobs as needed.
Your comment also gives me an idea about 'solutions' to maps... sort of inspired by 'closeness' in things like recommendation engines, maybe the path to a treasure merely needs to be 'close' to the ideal solution (the analogy would be like, a game that's a 90% "match" to Anodyne 2). I kind of like that, it might even fit with the theming of the story.
I wonder how the exploration (on a granular basis) would stay engaging, but with a game like Yume Nikki in mind, maybe filling rooms with strange sights and characters is enough? I guess this is a case where overthinking things would lead to perfunctory design (e.g. if it was combat-based, and I had to kill enemies with a Red Weapon to get to a Red Room... etc).

Thanks for writing your thoughts on the themes! While I plan to use the visual language of 'towns', this very much is a story that's thinking more about subcultures and types creative circles. I'm glad to hear that it sounds resonant so far!
Like you bring up with the internet, I guess this game is quite inspired by the experience of living on the internet.. ending up in strange places with surprising ideas, meeting or observing people with totally different interests and priorities is in general an enriching way to live, I feel. Actually, there's an old story/game idea (that's a partial inspiration for Shuffled World) I had that's basically analogizing discord servers and their relative isolation and connection. The way that 'invite codes' are sort of like these special passwords or tunnels to different 'discord worlds', etc.
Anyways, time will tell if I manage to work on any of this stuff but I'm glad that these posts are interesting as-is!
