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.)
If you are looking for other reviews, this ifwiki page contains a list of places currently carrying them.
Switcheroo is the third in a series of Undum children’s stories about Mrs. Wobbles, a foster parent who lives in a big mysterious tangerine-colored house with many foster children. (Previously reviewed here: Book 1, Book 2.) It is fairly linear but has an important choice near the end, and allows for some playful interaction in the middle as well, including a couple set-piece elements that play as mini-games. Once again I fail at accurate timing, but it took me less than an hour to read.
