So:
1) it sends you to a random stage from the gather well (or maybe random within a set 5 or so).
2) there's a consistent numerical order for the stages.
3} the glyphs above the wells (are not representative of the stages themselves, but) do some math to send you to a new stage (such as rise is +1).
I'm unsure how players could ever figure this out if they don't know the above by some means communicated in the game. Except maybe extreme trial & error, but even then they haven't deciphered the meanings of the glyphs, they are brute-forcing it. It's kinda like saying, solve: x + y = z . We've got nothing but unknowns to work with.
The main thing making it a big ask is the forcing of the time-consuming puzzle stages (2 so far I mentioned where you can't die) over and over.
I really think this is a case of the dev being unable to put themselves in players' shoes. You designed it so you have all the answers (plus you know all the good routes and safe spots).
I think the game is super rad. But yeah, this is a tad much.
