Advent of Code is an "Advent calendar of small programming puzzles for a variety of skill levels that can be solved in any programming language you like" made by a guy named Eric Wastl. In last years it grew a bit and now it has several followers.
In year 2019 there was a recurring feature that asked to write an interpreter for codes made by integer numbers, the Intcode, and fed such codes to solve some of the puzzles.
In the last day, the 25th of December 2019, if your Intcode engine worked, you could play a text adventure that contained the solution.
The adventure is solvable by hand or by writing an algorithm that explores all the locations, taking useful objects and ignoring the dangerous ones, and eventually parsing the final solution. The Intcode weren't the same for every account, so there isn't a unique solution.
I wonder if it could interest the archive and if so, how to put into the database (like: what to write for "platform"? maybe "Intcode"?)
