A mixed bag. On one hand, it does a vivid, colorful job of showing madness from the inside. The plot is generally decent, though at some point the ending becomes predictable.
On the other, it’s fantastically linear, with almost no challenge or logic to events. The story is told by a madman, inside his mind, and that leaves its mark on the gameplay: you can’t predict what you’re supposed to do in the next room.
So you wander around looking for triggers, trying to make sense of whatever weird thing comes next. A melting phone? Exploding clocks? Now and then, something really gets to you, like the letters between the hero and his wife. Those moments are rare, and they feel like a breath of fresh air.
Overall, I don’t regret playing it: it’s a sad, heavy story, with a lot of care put into the art and voice acting. But I suspect a lot of meaning drowned in its sea of symbolism.
