Passage is part game and part art, and was created by Jason Rohrer for Kokoromi’s Gamma256.
Gamma256 encouraged game designers to use the smallest and most irregular aspect ratio possible (and they were not to exceed 256×256) and do with it what they could.
The result was games like Passage, a “memento mori” game that takes a bit of getting used to.
My suggestion is this: Download, install, and play the game first. Then, go back and read the creator’s statement for a bit of an explanation, and the game will take on an entirely new meaning.
It’s not exactly exciting, but the game does approach design from a very different angle, and it’s refreshing to see what’s possible when the story trumps the graphics.
