in what way? I'm kinda interested in this game.
I wouldn't say it sucked at all. I thought the ending was great, but that might be due to the ending that I got. Had one played the game with less care, they might have got an entirely different and unsatisfying ending.
Without giving away too much, this is a mystery game. If you/your characters don't solve or at least make headway on that mystery, I doubt you'll be happy with the ending. It won't be a happy ending, it will instead be very depressing because YOU failed. Not quite the game over and try again that we're used to - main characters can and will die, or fail to be at the right place at the right time and that will obviously have drastic effects on the outcome of the story.
You will also have to make several morally ambiguous choices, the consequences of which are not apparent at the time, and that alone can be a bit uncomfortable. There is no way to complete the game as a true hero like most games.
In a way, my characters figured the mystery out before I did, but when it all came to a head at the very end I thought it was incredibly satisfying since my decisions accomplished the goal. It's entirely possible to make decisions and fail at certain tasks that completely derail the solving of the mystery.
