Labyrinth

This is a mid-length IFComp game from 2006. It's a surreal afterlife/coma type game where you've been in a car crash and must travel through your mind to escape back to reality, hopefully with your wife.

It has a maze of rooms, inaccessible at first due to the fact that doors and archways are placed on ceilings and high walls, willy-nilly. You eventually learn to control the maze.

Much of the game revolves around smells. There is a Nim game and also a difficult cryptographic puzzle. I found it under-clued and somewhat unfair.
