Undertale Yellow is so impressive not as just a fan game but as a game itself. I think an important way I go about understanding it is that it is not just undertale 2 or something like that, its trying to tell its own story and narrative that does tie into undertale lore but really is not that crucial to it. And the story it does tell I loved. The characters were amazing and I loved the questions concerning what justice is inside pacifist and genocide. I know some people complain about the bosses, but I loved every fight. Where they tough as nails? For sure, but the satisfaction that follows a win will always be remembered. Also every route has a awesome final boss, its crazy all 3 were bangers. I dont want to say much spoiler wise, so please just play. All routes is longer than base undertale but its all fun. Just try to think of it as its own product
