I just played through Today I Die and Don't Look Back, two art games, short and sweet. Like Passage. Worth playing.
Today I Die, aside from its artistic merit, represents the start of an experiment in a new monetization model for art games, beyond advertising or microtransactions. That is, patronage, or enhanced donations. Further discussion here.
Don't Look Back is a retelling of the myth of Orpheus and Eurydice, in interactive form. There are no words, other than in the title and instructions. To my mind, it really demonstrates the similarities between myth and games. I think there is a lot to explore here.
