Thanks for your detailed reply! Yeah I think setting up the hints more explicitly on Puzzle 0 is a great idea. Honestly the hints are extremely important to generating the "solution pressure" I was talking about all across the puzzle and while I completely understand them now with the curse of knowledge I think a blind player suspecting they are more complex than they actually are, or relate to some coordinate system, etc is a pretty reasonable concern. Explicitly calling them out as hints on the very simple Puzzle 0 should go a long way toward clearing up that ambiguity.
Thanks again for making this puzzle, after seeing the couple updates you did since the version I played it is very close to being a total masterpiece! And it is already very brilliant. As me and one of my viewers discussed, I think language-driven epiphany puzzles like this are just mildly cursed to begin with, and anything you do to make them more explicit/obvious robs them of their magic a bit. So I think you've done the best conceivable job of threading that needle with the updates you've made so far.
