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.)
Arcane Intern (Unpaid) is a Twine piece with three endings, in which the player goes to work at a publishing house that turns out to be tangled up with actual magic; it’s a branch-and-bottleneck structure with an intro, three segments with light puzzles and exploration, and a conclusion. I played to all three endings.
