As part of the IF Comp review collective project, I asked Stephen Granade — scientist and science educator, author of space escape game Fragile Shells, and former IF Comp organizer — to look at Life on Mars?. He came through in style with a Twine review that demonstrates his feedback interactively.
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.
Life on Mars? is a parser-based, puzzleless game by Hugo Labrande. It was originally in French, and won the French IF competition in 2014. It took me less than an hour to play, and I reached what I believe is the only available ending. (Until last year, translations of existing IF were forbidden in IF Comp because of the “no previous releases” rule; that rule has now been loosened in the case that the translated version has not been seen before. I’m really excited that this rule change bore fruit in the 2015 competition and that it is bringing some of these pieces to a new audience.)
