Night in the Woods is not at all based on game mechanics. It's all about story and, more specifically, about character development. I would say the "main story" is about a 10-20% of total game time, maybe even less. The main charm of the game is getting to know Mae's family and friends and finding out what happened to her. I adored every character, even when I didn't like how they acted or behaved, because they are insanely complex and they feel like real people with real problems.
