Well, I beat Child of Light already... ^^; I think it's like 10 hours of gameplay, but I played it in chunks of like 3-4 hours. It definitely feels like the ending of the game was rushed or something, but I won't mention why so as not to spoil anyone who plans on playing it eventually. I really hope they release some DLC chapteres or something, I'd pay another $15 for another 10 hours of story. :p
