Since I recently played it, I'm going to throw Thomas Was Alone in here.
It was a fun, competent platformer, with a nice story that didn't take itself too seriously, and an enjoyable cast of personalities. It was especially impressive how the gameplay reinforced the story's main theme of teamwork, by forcing you to use the blocks' unique abilities in tandem to progress. But come on, guys. Tears were not shed. I think I've got some hype aversion going on; if I'd played this just as an indie game, I would have regarded it highly for its style and theming. But I played it as one of the best game narratives of all time, supposedly even better than The Walking Dead, which had recently blown me away. Naturally, it failed to live up to those lofty expectations.
Also, the puzzles never got terribly difficult. On one level I was thankful for that, because none of them stood between me and the ending for too long. On the other hand, if they had strained my brain more, maybe the game wouldn't have whizzed by so fast, and I would have felt more satisfied upon finishing it.
