That mechanic is so creative. I love the gave but it's hard to describe what's so great about it to others without also revealing that brilliant mechanic which is really fun to encounter for the first time without expecting it.
A conversation vaguely pointing toward a key game mechanic that might have something to do with metatextuality but which mustn't be described for fear of spoiling it is a damn good way to get me to buy a game.
(Just purchased. Easy buy vs. wishlist decision since it's currently half-off on Steam)
Have you by chance played Tunic? If not, there is a mechanic you may be particularly interested in. :)
