It was an OK story, with some choice making and light puzzles. It's a bit more down to earth than the Life Is Strange series games, but I would still want to see Dontnod making a game completely without supernatural elements.
If you like narrative adventures then you'll enjoy this. Much like Life is Strange, this let's you experience a story with some intrigue but this has the added weight of a sibling bond at the heart of it.
Some parts are frustrating/slow to replay if you save/exit at a bad time but its decent enough overall.
