Thanks for including the source! It's helpful for a Twine newbie like me. Some things immediately clicked once I read it.
Although yes, I did, indeed, play the game first, and I recommend that to others!
I actually brute-forced the main puzzle and am pleased of the way I found to do so relatively efficiently, but obviously it was not meant to leave people stuck too long. (For the record, a guess I had was right, for the final alignment.)
The finale was well thought out, too. I've been surprised how many neat dungeon games there have been in Neo Twiny Jam!
