$14? Definitely.
More? no way. I've been playing through it (doing a Let's Play, actually), and it's... decent. While the combat is repetitive, once you get into it's rhythm, it just seems to not be there anymore. You stop noticing it being bad. The climbing sections are a bit like uncharted. I haven't gotten far enough in the story yet to judge that, but the silly names they give organisations and characters (Errorist, Edge, Bad-Request) either give you giggles or make you lose your sides, so it's entertaining enough, though not in the way the studio intended.
The one place where this game positively shines is art style and visuals. Remember Me is a beautiful game, and worth playing just for the way it looks. The first chapter in the slums is meh, but once you get past the first memory shuffle, it's real pretty.
I'd say go for it. For $14 you won't be dissapointed.
