You have got to see this game that a local writer, Jason Arment, shared with me:
Imagine Super Mario Brothers where Luigi walks around depressed, smoking and ruminating. That’s it. You can either walk left, walk right, ruminate, or smoke (and only one at a time, you can’t multitask). Nothing else. You can’t jump, win, or die. There are no coins, no enemies, nothing else. The Super Mario World is a ruin, and apparently random as you walk back and forth.
You’ve got to check it out.
