The loop is all about adapting, experimenting, and seeing which combinations work and which don't. Right now it's designed around mini-games which can have a different goal per game -- as a quick example I'm currently building agent tic-tac-toe but hidden trapdoors and power-ups

So strange. Like, it doesn't sound like there really is a proper loop that you have figured out. But this actually sounds exciting - like when you read about how certain game genres were emerging and game designers were almost accidentally discovering what is fun.
