I think it’s just nice QoL, not sure if it qualifies as accessibiity (although you could argue it’s of greater help to people with trouble with short term memory haha) - I think my suggestion to unlock it after a few tries might be a great compromise? You’re still forced to actually try but you’re not punished for a silly mistake later on? And I’d argue people that will play your game are people interested in the puzzle elements of it anyway, they’re not likely to use it to cheese their way through it (and if they do, they’re not the ones you want to advertise your game to anyway?) But I agree, it’s a lot to think about, there’s argument to both sides!
