The 21st annual Interactive Fiction Competition is currently on, through mid-November. Voting is open to the general public; the only prerequisite is that you not be an author, not vote on games that you tested, and submit votes on at least five games. (You emphatically do not have to have played them all! In a year with 55 entrants, it is very unlikely that most judges will get through anywhere near all of them.)
Summit is a mid-length, multi-stranded Twine game with visual effects and a soundtrack. (If you play, I strongly recommend making sure that you’re in a position to play with the sound on — it really is not the same experience without.) It tells a surreal fantasy parable in a world rather reminiscent of Porpentine’s work.
