sure! This Monster Wants to Eat Me/WataTabe is the big one, which you've probably already found but if not, I'd highly recommend it. Normality and Monsters is also really outstanding and dwells heavily on what it can mean to be a monster vs being 'normal'. Alcohol and Ogre-girls is another great one, with a really interesting central dynamic and a lot of great secondary characters too. The moment when the oni's monstrosity jumps out are pretty fantastic. Finally, check out At the Bottom of the Water - so far it's mostly subtextually yuri, but the vibes are impeccable and it leans a lot closer to horror than other examples in the genre, so if that's your thing, check it out
