At it's core, it's a playful mockery of video game storytelling themes. The writing is clever, and the narration is charming, while also managing to be just a little unsettling. It's a game, so much in that you control movement and press buttons. But there isn't any combat, and the freedom of choice is just an illusion (which is kinda the point). It's meant to be played over and over again, just to see the different reactions you can get from the game. And there are many many reactions to find.
And if this doesn't sound like something you'd want to spend any time with, you can always treat it like a really obscure easter egg hunt. Because there's a ton of those too. If you are like me, and you try to break a game just for fun, you might find out that this game considers it a legitimate storytelling branch.
And if that doesn't sell it to you either, you can consider it a narrator annoyance simulator. It's something for everyone, provided you like these three things.
