I believe that some of these have been reposted on Indygamer by the author, but the Arthouse Games blog seems like a neat new hangout for indie types.

For example, there's an interview with Nick Montfort about text adventures, with the following rather lyrical answer re: puzzles in IF: "I don't think puzzles are mandatory, nor do I think that IF authors have to go out of their way to create puzzleless work. There's a very successful and long-lived tradition in poetry of the riddle poem, which the reader or listener is asked to figure out, to solve -- while also appreciating the beauty of the language that makes up the riddle."

There's also a review of fl0w for PC, which rather interestingly says: "I highly recommend giving flOw a try, with the warning that it doesn't have much depth. It's a 10-minute experience, perhaps, but I don't think it aims to be anything more than that." Wonder how they're gonna fix that for the PS3 version?
