I could have sworn I heard about this on the GWJ forums or podcast, but I can't find mention of it in either.
Passage by Jason Rohrer
A submission for Koorumi's gamma 256 contest for games with the most irregular aspect ratio, and could not exceed 256x256.
The game takes all of 5 minutes to complete; a gaming parable if you will. Sweet and touching and even a little bit sad. All conveyed with simple 8 bit graphics and sound.
