Crazy monsters like Woshua, who just wants you to be clean, and a ghost who only lowers his HP when you attack to be polite. His brother Sans, mocking RPG puzzles by just dumping a Junior Jumble to block your way. Papyrus, the skeleton guard desperate for recognition and friends. After a slow and not particularly fun intro area, it opens up into a world more densely packed with jokes and puns and adorable characters than pretty much anything out there. It’s partly that, sure, and it’s brilliant at it. The basic secret is that it’s not entirely what it looks like: a goofy 8-bit RPG parody that owes a debt and at least two limbs to EarthBound/Mother.
