Inside's ending is one of the most confounding conclusions to a game in recent memory, which can make the story feel unsatisfying or even incomplete – but with a little bit of additional insight, perplexed onlookers can find meaning in the final sequence. Getting to the end of Playdead's puzzle platformer is challenging in and of itself; after all, it'll require problem-solving with little to no help, aside from the occasional guidance of a spotlight. Despite all the trouble it puts players through, the end result seems, on the surface, like nothing but oddity and vagueness.
