This is probably the most unpolished game I've seen with "overwhelmingly positive" reviews - probably because of childhood nostalgia and Westerners loving Japan. It is charming, too. As a pretty patient player I agree that it's worth it.
The game captures what it's like to be a child visiting grandma with nothing special to do. I found myself slipping into the role, just roaming around and leaving things on the floor, doors and windows open, exploring everything. As the game progresses, we see the kid's vivid imagination represented in the environment. The house and interactions, for me, are a mixture of familiar 90's or so and an interesting glimpse into Japanese culture. The rainy visuals and sounds are impeccable.

If the controls and interactions with items were better, this would be a perfect little walking sim. It's still a pleasant hour, or less if you're in a hurry. But why would you play this game while you're in a hurry?
