It's a captivating story that unfolds in a way that makes more sense as you go, leading you to understand the characters and their relationships to each other. I went into my first playthrough completely blind, so my understanding was absolutely zero when I started and the first few sections made no sense whatsoever, but this didn't at all take away from my experience. It made it more rewarding when I began putting pieces together.
The game's only weak point is that it is more of a story than a game, and interactivity mostly comes down to different choices of dialogue. I understand that this was a choice on the creator's part, and I definitely still recommend giving it a play-through, but it's best to be aware going in that you're going to get a non-traditional, non-linear story rather than an interactive adventure with puzzles.
