Despite the name, One Monster RPG isn’t really an RPG. It’s set at the very end of an adventure where you’ve killed every single monster apart from one. There are no more quests or mystical artefacts or bosses—there’s just one baby slime.
Killing the slime is easy. It’s level 1, while you’re level 99. One hit and it’s a goner. Unfortunately, it won’t give you enough experience points to get to level 100, the true goal of One Monster RPG. That really only leaves one option: feed that slime. Feed it until it’s a gargantuan monster that can swallow buildings whole.
All you need to do is let the slime chase you around, making sure that you lead it to things it can snack on. Dogs, children, farms—they’re all fair game. It can’t eat anything that’s a lower level, and if it catches you it’s effectively game over, as your only option is to kill it.
