[Ah, playing my turn for today reveals that either each player sees a different set of wall images, or -- even more interestingly if true, given the way this game is playing with time on the most basic level -- the wall images change each day.]

It’s also interesting that there’s ambiguity as to whether the gaps on the top and bottom toward the left are actual wall openings or whether they’re just an accident of the framing. (All walls on the first screen except the one on the far left have those notches. My guess is that either those are solid walls on the top and bottom or else the entire corridor is porous. Probably the former.).

Lastly, someone on Twitter was recently complaining that they can’t enjoy even single-player games these days because — and I might be mangling their sentiment here, possibly because I couldn’t relate — the field is already full of “power” players or “FAQ-based” players, leaving no room for solitary exploration of a game’s language/intricacies/game-rules(?). In any case, it’s interesting that this game’s set-up seems to sidestep that issue, at least for anyone starting within the first few days of its release (and assuming no one cheats the system and maps the whole thing out at once).

[Also, there's probably a sly comment to be made about in-app purchases and/or reports of players selling their save-files, but I can't quite get it together.]
