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.
I.e. what's the goal, how do you know you're doing well (or not), what makes it fun etc?
