At Pax, it was a mishmash of big industry gaming, gamer culture, academic presentations and local gaming scene. For Indie Games, I was lucky to see Meigakure produced by Marcten Bosch. The concept of navigating on four planes of existence to acheive a goal is no small matter.
Concept: You start on one plane and open additional planes, which you navigate by moving blocks and shifting from plane to plane. Your goal is to reach an exit on the other side of the board, but you must activate the other planes and collect power ups along the way.
The comic, XKCD somehow distills some of the more mindbending aspects of the game. I’m looking forward to when this ships.
