Advent Mirror is a Glulx interactive fiction game written with Inform 7 and is © 2022 by Andrew Plotkin. It was an entry in the Confounding Calendar 2022.
In this sequel to Advent Door, you are once again a Traveller in the City of Doors. Where has the portal taken you? Featuring a very interesting and tall mirror.
This solution is by David Welbourn, and is based on Release 2 of the game.
