While technically IF, "Lifeform" is more like an online teen survey ("What is Your Inner Spirit Animal?" "Which Gilligan's Island Character Are You?") than anything else. Except that, unlike a teen survey, it is funny, well written, and not a complete waste of time. Although it's a hypertext game, it is not tedious like the Twine genre and is ultimately an enjoyable, quick, puzzle-less diversion worth playing once or twice if you feel like something light. Or you could fill out a Meyers Briggs Test. The results may be remarkably the same.
