I never get farther than 1 or two choices of doors. Then boom, back to the beginning.

Has anyone gotten further than that?

Yep, I've finished it a couple times. It is definitely possible, but it's just dumb luck whether you get through or not. There isn't a trick or pattern to it.

I think there are 9? total rooms before the treasure

yes, I made it through once on the original settings and several times after they made it easier. I haven't made it through in months though I have gotten close a few times. Most tries are 1-3 rooms, but depending on how often I play, I usually get further than that once or twice a month.

I’ve made my way to the end 41 times. Pick your path (i.e. always choose the same set of doors - this helps stop second guessing yourself and feels faster) and try it whenever you remember. Don’t expect to win so you don’t get disappointed. Don’t give up!

Yep. I've gotten through a few times as well. Always use the same route. But it really is just dumb luck. Same as with the ice fields and the safe. Same route/code everytime and eventually you'll make it. Just keep trying :)
