CaveFiction is a terrible game. Being a philosophical he AVG game designed to keep you constantly alert, not only is the gameplay sleepy, but the cast of characters is terrible. Each serves no purpose to the story, and at worst is the main character's Plan. He starts off as someone who wants to break up with his girlfriend, but even with the really big plot twist, he doesn't look like he's changed at all. You are the same person before and after becoming an adult. All in all, it's a terrible game if you want that kind of game, but it really ticks all the boxes for a great story that fits the fast pace of modern society.
Play Nekopara.
